How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

What causes excessive cat grooming? The two main causes for overgrooming are behavioural, when the cat starts licking excessively as a form of stress-relief (also known as psychogenic alopecia), and medical, when skin allergies or skin parasites are the main culprit.
A Depressed Cat Might Have Changes in Their Eating Habits

This most often manifests as a loss of appetite or a decrease in food intake. This is obviously a concerning cat depression sign because it can cause your cat to lose weight and suffer negative health impacts.

If cats feel good, they will keep themselves well groomed. A cheerful kitty will also groom other cats or even lick their owner – this also shows trust and a positive relationship.
A change in grooming habits can be an indicator of depression. Some depressed cats will stop grooming altogether, while some start over grooming themselves, leaving irritated skin and even open wounds.
The most common signs of overgrooming are hair loss and irritation of the skin. The areas usually affected are the abdomen, legs, flank, and chest, as these are the most easily reached areas. You may also notice: Grooming when it`s no longer functional or when it interrupts your cat`s other activities.
However, they may perceive things from a different angle. Cats are able to sense sadness in a way that they associate the visual and auditory signals of human sadness such as frowning and a listless voice with how they are addressed or treated whenever their human is in a sad state.
Cats are big fans of cleanliness—especially when it comes to their litter box! If your kitty`s litter isn`t clean, they may even “go” elsewhere (such as on your carpet) to avoid using a messy or smelly litter box. Therefore, scoop any waste and leave your cat with tidy litter in an accessible area.
Cons of Indoor Cats

Because cats enjoy roaming and exploring, keeping them inside can lead to boredom. Some indoor cats also experience depression and separation anxiety. To prevent these issues, you must take steps to meet your cat`s needs.

Cats will miss their owners when they are gone, but the response to a cat missing you may vary. Some kitties may express their sadness through purring, meowing, or following their owner around, while others may show no outward signs of sadness.
If your cat is over-grooming you will notice patches of broken or sparse hair, complete hair loss in areas and occasionally damage to the underlying skin. In extreme cases a cat may chew or bite, usually its feet or tail, causing trauma that may require, in the case of the tail, partial amputation.
Bonding. Cats groom each other and around each other to bond with other cats. Cats that groom their owners or grooming on their owners is that cat bonding with their human. This is your cat`s time to spend valuable time with you.
This symptom is most commonly associated with food allergies that cause skin problems. However, cats may also lick their paws obsessively if they have seasonal allergies, pollen allergies, or contact allergies, depending on the individual cat and situation.
Recovery of Depression in Cats

The recovery process will vary depending on the cause of your cat`s depression. For most cats without underlying health conditions, depression is short-lived. Cats usually bounce back quickly once their humans change their environment or routine to better suit their needs.

Cats don`t cry tears when they`re sad or in pain. But Halls says whether your cat is experiencing emotional or physical pain, they`ll exhibit behavioral changes that could include vocal crying. The sound of a cat crying is typically longer in duration and lower in frequency than day-to-day cat chatter.
The 2016 Animals article mentioned above found that the behavioral changes observed in cats following the loss of an animal companion usually lasted for less than six months.
Cats are often stereotyped as standoffish and aloof, even to the people who love them most, but the truth is that cats can be just as protective of their people as dogs are of theirs. Put simply, cats love their family and their family loves them right back.
Either way, there`s evidence that cats comfort humans when sad. “When pet parents are depressed, cats rub against them more often. It`s likely your cat is responding to your emotional state by trying to comfort you or draw your attention,” McGowan says.
Cats can sense how people are feeling, so your cat actually can tell when you`re sad. “Cats can definitely sense when you are sad because they are highly attuned to your normal behaviors and moods, and if there is a change, they sense it,” Dr. Wooten told The Dodo.
It`s a question that many cat owners have wondered. And the answer is a resounding yes! Cats often feel love quite strongly for their owners and other companions. They`re just sometimes a little more subtle about it than dogs.
You might think that with the 15 hours a day your cat spends napping that she may not have time to get bored. But unfortunately, cats can—and do— get bored.
Cats, while often independent creatures, still crave attention and love, in addition to their obvious nutritional needs of fresh water, clean litter, and food. If you decide to bring a cat or kitten into your home, you should be prepared to spend at least 20 minutes a day giving your cat loving one-on-one attention.
If you are going to have your cat inside, it is important to make its environment as stimulating as possible. If you don`t, cats can quickly become bored, stressed and even depressed, resulting in detrimental and destructive behaviours.
Cats like peace and quiet. Household conveniences, like vacuum cleaners, can easily disrupttheir nap time.

Q. Why do cats meow?
ANSWER : A. Cat parents often wish they could better understand what their favorite feline friends want or desire. A cat’s meow can be interpreted in many different ways and can indicate an array of feelings and needs. Here are some of the most common reasons for your cat’s vocalizations:

1. Greeting- Many cats will meow as a greeting when you enter your home or walk into a room. Cats will also meow at another cat or animal in the household to extend a hello and acknowledge the other animal’s presence.

2. Attention – An exuberant meow followed by leg rubbing or another attention seeking behavior may indicate your cat is looking for some quality time spent together. Some petting or rubbing behind the ears may be in order.

3. Hunger – A meowing cat is often a hungry cat. This is one of the most common reasons for a cat to vocalize to their owners. A cat will meow to get your attention at feeding times or even when they want extra food.

4. Sickness – A sick or hurt cat may begin to meow excessively, warranting a visit to the veterinarian. There are numerous reasons for a cat in distress to meow—whether it is related to an upset stomach, an injured leg or a urinary blockage. These meows should be carefully investigated.

5. Entering or leaving – Most cats will vocalize when they want to be let in or out of a room. You may notice when you are in the bathroom or behind the closed door of a room that your cat begins to meow, scratches at the door, and often reaches its paw under the door. This is a clear indication that the cat wants to be where you are.

6. Angry – An agitated cat may meow to warn their owner or another household pet that they are upset and would like to be left alone. This angry meow may increase in sound volume as the cat becomes more stressed or agitated. Often a cat will exhibit this type of meow at the veterinary office when they are unhappy with their examination or restraint.

Each feline is different and so are their vocalizations. Learn to understand the variety of meows your cat uses on a daily basis. This will help you develop a better relationship with your cat and help them live a more trusting and happier life.

Q. My cat continues to scratch on furniture and carpets. He has plenty of scratching posts around the house. Please help!
ANSWER : A. Scratching is a natural behavior in cats that can be frequently frustrating for pet owners who want to keep their furniture from being shredded on a constant basis. The texture of furniture and carpet is very appealing to cats and this why they frequently choose to spend their time on this activity as opposed to playing with their own cat toys. Here are some suggestions to help curb this unwanted behavior:

1. Purchase a cat scratching post or cat tree that is covered in carpeted or textured material. Place it in an appealing spot that your cat would be inclined to spend time (eg. in the sun). You can also place catnip on the scratching post or cat tree to make your cat even more interested in the new object.

2. You can utilize double sided tape on the ends of the furniture because you cat will not like the sticky feeling and will learn to not scratch in that region. Use the tape that has a lighter adhesive in order to prevent any permanent damage. Other materials, such as aluminum foil or bubble wrap can also be placed on the furniture to discourage the scratching.

3. Keep nails trimmed short by either learning to do this on your own at home or using a veterinary technician, or groomer. Nails can usually be trimmed every 6-8 weeks.

4. Redirect the unwanted behavior. If your cat begins scratching, use a favorite or new toy to distract the cat from the scratching. Give your cat positive praise for not scratching.

5. As a last resort you can use a spray bottle full of water to spritz your cat when he or she is scratching inappropriately at your furniture. Generally, cats do not like water and this will discourage them from continuing the behavior.

Have patience with your cat because it can takes time to understand this is an unwanted behavior and that furniture is not another toy for them to use. You can always consult your veterinary or veterinary behaviorist to help with ideas or further solutions to this problem.

Q. Cat was vomiting for a few days. Took to vet, received anti-nausea medicine 2 days ago. Drinks and no longer vomits, but won’t eat. I’m worried
ANSWER : A. If your cat has been feeling nauseated, it is possible that the nausea, or just general illness is making him want to eat less. However, you can try enticing him to eat with a few tricks geared to cats.

Warming up wet foods or even bland people foods such as plain chicken or boiled hamburger can make food more interesting to cats. Cats tend to go for aromatic rather than flavorful foods, so making the food as “smelly” as possible may encourage your cat to take a bite. Bland foods are also good for helping to soothe upset stomachs, which may still be happening if your cat had recently had a vomiting episode.

However, if enticing your cat to eat does not work, or he continues to refuse to eat any food, it is best to contact your local veterinarian for more care and testing. Cats can become very ill if they refuse to eat for more than a few days, and finding the underlying cause can help your cat feel better.

Q. My cat is pooping outside of the litter bix. He is 2 1/2. He did this as a kitten. It stopped then started about 3 months ago. Litterbox is clean.
ANSWER : A. Inappropriate elimination or house soiling can be a frustrating problem but with a bit of detective work on your part, there is hope. First, before deciding that this is a behavioral issue, any medical problems (diarrhea, constipation, fecal incontinence, pain on defecation, etc.) need to be ruled out and/or treated. If your cat receives a clean bill of health from your vet but is still eliminating outside the litterbox, then we need to consider that something about the box itself might be aversive to your cat. Cats can be quite finicky about their litterbox and toileting habits. Below I have listed common recommendations and cat preferences for litterbox use. Review the list and make any changes that could account for your cat’s aversion to defecating in the litterbox:
* Soft, fine-grained clumping litter (vs, coarse-grained, non-clumping litter)
* Unscented
* 1 – 1 1/2 inch depth (especially older cats or cats with hip problems)
* Larger pans (especially for large cats) – want to get whole body inside – poop just outside the box might mean the box is too small
* Open, non-hooded
* At least one shallow side to get in and out easily
* Easy to get to – not hidden away, preferably in areas they spend time in or near – and not near appliances that make scary, unpredictable noises (washers, dryers, refrigerators)
* Scoop minimum 1X/day – preferably 2
* Clean the litterbox with soap and water and put in fresh scoopable litter at least once/month (instead of just continuously adding)
* Some cats prefer to urinate in one box and defecate in a separate box, so you may need 2 boxes even if you just have 1 cat. Multi-cat households should have 1 box/cat plus 1 extra.

Q. We have two female cats who are sisters. One was just diagnosed with generalized lymphoma. Is there risk of being contageous? What kind of food
ANSWER : A. Lymphoma is a cancer and not a bacteria or virus, so it cannot be spread from cat to cat via contact. However, if your cats are related, they may both be genetically predisposed to getting the same type of cancer. Feline lymphoma can also sometimes be caused by the Feline Leukemia Virus (FeLV) or Feline Immunodeficiency Virus (FIV) which CAN be spread from cat to cat. The spread of these viruses is usually through bite wounds, saliva or fecal and urine matter, and the chances of spread among two amicable cats is lower, however testing both cats is always good.

As lymphoma can cause a decrease in appetite, sometimes the best food is one that will keep your cat on her normal eating routine so that she keeps her weight and energy up. Enticing her to eat by warming up wet foods, or even moistening and warming dry foods may encourage continued normal eating and may prevent weight loss from loss of appetite. A high-fat, high protein and low carbohydrate diet (such as a grain-free diet) may also help by providing a more calorie and nutrient dense meal so that every bite is beneficial.

Q. How should I interpret my cat’s tail movements?
ANSWER : A. Our feline friends express themselves in many different ways, including through the use of their tails. Most pet owners pay close attention to a happy or excited dog, but they are sometimes less attentive to the posture and movement of their cat. Here are some of the most common cat tail behaviors, and the underlying emotion behind each action:

A flicking tail: Many anxious, nervous or stressed cats will hold their tail in a low position and flick it quickly back and forth. This is often referred to as angry tail, and a pet owner or veterinarian should be on guard for any possible aggressive or defensive activity. If a cat is moving their tail slowly, and not exhibiting the flicking motion, then this cat is at a much calmer state.

Vertical position: Most of the time when a cat is holding their tail in a straight, vertical position this is indicating curiosity and a playful mood. A cat chasing after a laser pointer or playing toys will often have their tails in a vertical position showing their enjoyment. This position also helps with balanced movements. In contrast, if the tail is in the vertical position and the cat’s back is arched with pinned back ears then this could demonstrate a feeling of being threatened and thus result in defensive or aggressive behaviors.

The Tucked Tail: Similar to a dog, a tucked tail often indicates submission or fear. Your cat is conveying upset feelings and should most likely be left alone. This tucked tail appearance can also make a cat look smaller and less threatening to an aggressive cat.

The Tail Twine: Cats will often hook their tail around another cat’s tail, owner’s legs or other objects to show a friendly and affectionate nature. They are also trying to indicate whether they want to receive affection from their owners, be fed or have playtime.

The next time you are home with your feline companion take note on how they express themselves through their tail movements, their ears, body posture and vocalization. You can start to better understand their needs and wants, in addition to what makes them uncomfortable or happy. Cats will surprise you with their array of emotions and varied expressions they can express.

Q. I want to know from a veterinarian that has owned indoor cats if they agree with declawing? Also, is the whole digit still removed?
ANSWER : A. I am not a veterinarian, but a certified dog trainer. I have studied cat behavior as well, so I have some knowledge in that area. Cats need their claws in my opinion. When a cat is declawed, it can sometimes cause serious anxiety and frustration in the declawed cat. This is because the cat can not de-stress by digging at a scratching post, and a cat feels defenceless without its nails. It is a sad sight to see when a cat who is declawed is dealing with anxiety. I’ve met declawed cats who seem very unstable. It’s difficult to tell whether or not the cats would be so unstable had they not been declawed, but I’ve never seen a cat who has all of its nails act the way a declawed cat acts.

That’s just my two cents.

Q. My cats nose is stopped up on antibiotics. She has a loss of appetite, acting normal though. Is 3 ounces of can food enough in 24h? 9 pound cat
ANSWER : A. Cats with stopped up noses tend to eat much less, as you’ve noted, because they can’t smell their food as well. And the smell of food is pretty important to a cat’s appetite. You can start by warming up the food in a microwave – not too hot, test it yourself by putting your finger right in the center, as the temperature of microwave food can vary – as this will intensify the smell and hopefully make your cat more interested.

Saline nose drops, like those that are used on little kids, are safe to use on a cat to clean the discharge that is dried around and in the nose. There’s a brand called Little Noses that’s available in the U.S. That I like. You can put it on a q-tip and try to remove the debris. Humidifying the air with a humidifier can help as well, or you can put the cat in the bathroom and run the shower enough to generate steam. Don’t use “real” nose drops like Neo-synephrine or anything else like that – cats quickly build up resistance to them.

A 3 oz can of food is an OK amount in 24 hours, but do try the techniques above to help your cat get more interested in food. You might also try some baby food – no garlic or onions in the ingredients – as cats usually really like the taste of it.
