How to Identify Common Pet Problems ?

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

Kitten diarrhea can be caused by food allergies, parasites, and bacterial and viral infections. As diarrhea itself is a symptom of illness, it`s essential to consult with your veterinarian if your kitten is exhibiting signs of diarrhea along with other symptoms.
What are some causes of diarrhea? Infectious agents, such as bacteria, viruses, coccidia, and intestinal worms (hookworms, roundworms, whipworms), or non-infectious irritants, such as chemical toxins or poisonous plants, are some of the more common causes of diarrhea.
Like human babies, kittens can be sensitive to sudden changes in environment or diet. They can even suffer from food allergies. These factors can cause diarrhea, a condition in which the kitten will release frequent, liquidy stools.
How long does kitten diarrhea last? Diarrhea in kittens doesn`t usually last more than two to three days.
Generally, you will keep your cat on a bland diet for one or two weeks. During that time, continue feeding small amounts every 3 to 4 hours. If the diarrhea goes away, then over another one to two weeks, you will slowly transition them back to their regular cat food diet.
Healthy cat poop should be brown in color, well-formed, and firm. While most shades of brown cat poop are normal, any abrupt changes in color or texture should be monitored and reported to your vet. Unhealthy cat poop may have a soft or runny consistency and be difficult to scoop; it may be very hard and pebble-like.
Overfeeding kittens, especially those who are underweight or malnourished, is a common cause of diarrhea. Therefore, for the first 24 hours of feeding a bottle baby, dilute the kitten milk replacer formula.
Can you overfeed a kitten? From a kitten`s first few weeks of life up until they reach four months, their metabolism is at its all-time high as they are constantly growing and using larger amounts of nutrients. It`s almost impossible to overfeed your kitten during this time.
Poop and litter should not be flushed into municipal sewer systems either, because many of them cannot eliminate Toxoplasma, a rather nasty organism sometimes present in cat waste; its release into the ocean has been known to kill sea otters.
Why does my cat have diarrhea but is acting normal? Your cat may be having a slight response to something they ate if they have diarrhea but otherwise appear okay. However, even if your cat appears to be performing normally, bacterial or viral illnesses can cause gastrointestinal symptoms and pain.
Unflavored psyllium (e.g., Metamucil) and canned pumpkin are two easily available fiber supplements. No hard and fast rules for how to dose psyllium or pumpkin in cats exist, but starting with 1-2 teaspoons of either mixed into your cat`s food over the course of the day is a reasonable place to start.
However, if your kitten has diarrhea but is acting normally, you can wait a day or two before contacting your vet. If the diarrhea continues, visit your veterinarian. Days of diarrhea can lead to dangerous dehydration in kittens.
You should know that it`s normal for kittens to have softer poop, Demos says. A kitten`s stools are not quite as dry and hard as an adult cat`s. But if your kitten`s poop is consistently shapeless and mushy or is liquidy, then it`s diarrhea. Kittens with diarrhea may have accidents outside the litterbox.
In many cases of simple diarrhea in adult cats, it is recommended to withhold food for 12-24 hours, and provide small amounts of water frequently. Then, a bland diet such as boiled (fat-free) chicken and rice is offered in small amounts.
Yolken: It is true that some cat poop contains Toxoplasma gondii, a parasite for which cats and other felines are the definitive host. This parasite can affect the fetus if a woman becomes infected while pregnant.
Kittens have very sensitive little stomachs and simple changes to their environment or diet can easily lead to diarrhoea. While it`s normal for their waste to be softer than that of an adult cat, if it`s shapeless or has a liquid or mushy consistency, it`s highly likely that the kitten has diarrhoea.
Feline panleukopenia virus (FPV), often called feline parvovirus, is a highly contagious virus that can cause diarrhea and gastrointestinal upset in kittens. It is common in kittens that are 2-4 months old, but it can happen at any age. The virus is very resilient and can survive for years in the environment.
Milk, cheese and other dairy products – Cats don`t tolerate dairy very well and can become lactose intolerant. Ingesting dairy products can cause vomiting and diarrhea for affected felines.
One of the biggest telltale signs a feline`s feeling famished is when you hear them meowing. While it`s perfectly normal for a cat to cry if they want feeding – and nothing to be concerned about – we do need to be sure hunger is the reason for any sudden vocalizations.
When kittens are getting enough to eat, they`ll get a nice big fat belly. Well-fed kittens won`t feel too ribby over the back. If you have food down and the kittens are eating it, your cat will self-regulate. If your kitten is not eating, then you should be worried and take them to the vet.
Is dry food better for cats with diarrhea? If wet food is too rich for your kitty, then switching over to dry food can absolutely help to alleviate the symptoms of diarrhea. However, wet food has a much higher moisture content than dry food, which helps to keep your cat hydrated.
Depending on the type and severity of infection, worm infestations that remain untreated can lead to serious health issues for your cat – including malnutrition, severe anemia, and intestinal obstructions – which can become life-threatening.
So how do indoor cats get infected with worms? Indoor cats will hunt just about anything in your home. Rodents, insects, and other household pests harbor worm eggs, which are passed on to your cat when he devours them. Mice and the common house fly are just two of the many critters that can carry roundworms eggs.

Q. Whenever I take my dog on walks he always barks at people and others dogs in my neighborhood. What should I do to resolve the problem
ANSWER : A. The very first thing to do is to make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good, happy dog and one who is less likely to bark from boredom or frustration. Depending on his breed, age, and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.

Figure out what he gets out of barking and remove it. Don’t give your dog the opportunity to continue the barking behavior.

Ignore your dog’s barking for as long as it takes him to stop. That means don’t give him attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to, don’t touch, or even look at him. When he finally quiets, even to take a breath, reward him with a treat. To be successful with this method, you must wait as long as it takes for him to stop barking. Yelling at him is the equivalent of barking with him.

Get your dog accustomed to whatever causes him to bark. Start with whatever makes him bark at a distance. It must be far enough away that he doesn’t bark when he sees it. Feed him lots of good treats. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If the stimulus moves out of sight, stop giving your dog treats. You want your dog to learn that the appearance of the stimulus leads to good things.

Teach your dog the ‘quiet’ command. Oddly, the first step is to teach your dog to bark on command. Give your dog the command to “speak,” wait for him to bark two or three times, and then stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say “speak.” Once your dog can reliably bark on command, teach him the “quiet” command. In a calm environment with no distractions, tell him to “speak.” When he starts barking, say “quiet” and stick a treat in front of his nose. Praise him for being quiet and give him the treat.

As in all training, always end training on a good note, even if it is just for obeying something very simple, like the ‘sit’ command. If you dog regresses in training, go back to the last thing he did successfully and reinforce that before moving on again. Keep sessions short, 15-20 minutes max, and do this several times a day.

Q. i believe my cat is pregnant but showing signs of being in heat
ANSWER : A. Cats are induced ovulators, meaning they will continue to go into heat until they are bred, or spayed (reproductive organs removed). If your cat is showing signs of being in heat (excessive yowling, presenting her rear to you for inspection, attempting to get out or other cats hanging near your house) and you don’t want kittens, it is best to have her spayed. Most cats are also semi-seasonal in their heat cycle meaning they will more likely be in heat through Spring-Summer than in Fall-Winter.

Pregnancy in cats lasts about 60 days. Signs of pregnancy may include weight gain, increased appetite, nipples that become pronounced or “leak” and seeking nesting areas to deliver kittens. If you saw that your cat was in heat, or had her mated, you can use the date she was bred to determine when she may be due for kittens. Your local vet can help determine if she is indeed pregnant and can also take an X-ray to determine the number of kittens present if your cat is nearing her due date. Be sure to feed mom a kitten formula in the last few weeks of her pregnancy and during nursing as it will help provide extra beneficial nutrients for both mom and babies.

If you do not want kittens, some very early term pregnancies can be aborted with spaying, otherwise spaying mom is usually done when kittens are weaned from their mom.

Q. I have a 1yr old male 38 lb Labradoodle and my gf just brought a month old kitten home. Can they interact? If not, for how long?
ANSWER : A. Interactions whenever a new pet is brought into the house should start off slow, then can be increased in time. The best steps when introducing a new cat is to allow your cat or kitten to have a room in the house all to him or herself. Allow your dog to sniff under the door to get used to the kitten’s scent, and even show your dog articles such as bedding the cat has slept on. After a few days, an introduction with your dog on leash, or a barrier such as a gate where both pets can look at each other but not see each other is best. This will allow each to get used to seeing the other without the ability to jump, bite or scratch the other. Once the two are used to this, then a face to face interaction can begin. If at any time a fight or scuffle breaks out, separate the two pets and try again at a later time. The amount of time this introduction takes can vary depending on how the two react to each other.

Until your kitten is older, or you are sure both are fine together, do not leave the two pets together unattended. Even a well-meaning and playful dog can accidentally break a leg of a kitten or worse without meaning to! A safe room for your kitten to be in while you are away, or a barrier to allow your kitten to escape to safety if needed will help until both are big enough to play alone safely.

Q. We brought 2 new kittens home. One of them is sneezing. We have a Sr cat and an adult who is now coughing. What to do?
ANSWER : A. Commonly respiratory infections (viral -Herpesvirus and Calicivirus- and possibly bacterial) can cause sneezing episodes in kitten especially if not vaccinated yet. If your kitten is affected by respiratory infection could develop or have more signs such as discharge from eyes, more discharge from nose, coughing, being lethargic, depressed and inappetent.

The coughing episodes of the adult cat could be completely unrelated to the cause of sneezing of your new kitten, especially if your adult cat is already vaccinated.

The cause of cough in adult cats are not necessarily related to respiratory problems, heart problems could cause that as well.

Keep the nose and the eyes of your kitten free from discharge, keep your kitten warm and take both of them to your veterinarian as soon as possible to identify the cause and the relationship of the two problems and treat appropriately.

Q. Can you give a Pit Bull a pork chop bone and can you give you dog chicken and rice for a treat
ANSWER : A. I wouldn’t recommend giving a pork chop bone even if it is raw (never give any dog any type of cooked bone) as they are small and could cause problems if eaten. You can give chicken and rice if you like occasionally but it isn’t good on a regular basis as it doesn’t contain all the required nutrients.

Q. I have two 3 week old kittens that I am bottle feeding. The kittens both have diareaa and there buts are red. Is there anything I can do ?
ANSWER : A. Diarrhea in kittens can be caused by many things, including intestinal parasites (very common in kittens), wrong formula, recent changes in diet (from queen’s milk to formula or from one formula to another), and other gastrointestinal upsets. Their bottoms are likely red and irritated from the diarrhea soiling the fur and skin, trapping moisture against the skin and serving as a breeding ground for bacteria. First, stop feeding the formula. Second, collect a fecal sample to be analyzed by your veterinarian for intestinal parasites. Third, call your vet and make an appointment as soon as possible, ideally the same day. Diarrhea in kittens is serious business and can lead to death from dehydration and loss of nutrients. Finally, in place of formula give an electrolyte replacement solution (like Pedialyte for infants/children) – plain, no flavors, no colors – for at least the next 1-2 feedings. This is not the same as a sports drink. After the 1st or 2nd feeding of straight electrolyte replacement solution, start to add formula back into diet at 1/4 strength ( 1 part formula to 3 parts water), The following feeding mix 2 parts formula to 2 parts water. Then, 3 parts formula to 1 part water. Finally, offer full-strength formula. If the diarrhea continues or worsens with increasing amounts of formula, go back to just electrolyte solution and repeat the process.

Q. I recently added a new 2 month old female kitten to my house and my male 5 month the old kitten has turned aggressive and chases the kitten down..
ANSWER : A. It is possible it could be play behavior but without seeing it in person, hard to say. Is the male kitten neutered? You may want to consider doing so. Also, try re-introducing the kittens slowly by creating a safe space for the new kitten behind a closed door in a room. Keep her there for at least a week so she is protected but your male is still able to smell her. After a week or 2, you can then graduate to using a baby gate so they can then not only smell each other but safely see each other as well. If that is going okay, after another few days you can bring the gate down. Also, be sure to have feeding bowls in separate locations and at least 2 litter boxes.

Q. How old do kittens have to be before they can be dewormed?
ANSWER : A. Kittens can be dewormed as early as 2-3 weeks of age with an appropriate dewormed that is safe for use in kittens. They are then usually dewormed again about a month later to treat any reinfection or remaining worms that may be present. If worms are present, deworming the mother cat (if safe to do so) may also be needed.

The most common types of worms seen in cats and kittens are roundworms (long, spaghetti-like segments in the stool or vomit) and tapeworms (small, rice-grain like segments that break off separately and shed in the environment). As these two worms are treated differently, knowing which one is present is best for providing the right worming treatment. If you are unsure about the product to use or the type of worm, bringing in a sample to your vet can allow them to find and provide the correct and safe worming medication.
