A. Neutering can change the hormones in your cat, so he may begin to gain weight and sleep more as he settles into a more “housecat” lifestyle. Keeping him active with interactive toys, limiting excessive treats and feeding a healthy diet can all help to keep him in better shape. If he is very lethargic suddenly, however, or is showing other signs of illness in addition to this, then scheduling a checkup with your local veterinarian to make sure there are not any underlying issues is best.

Recovery Immediately After the Procedure

In the first 24 hours after surgery, you`ll notice your pet may act groggy and sleep a great deal, which is entirely normal. The impact of the anesthesia may cause your cat to act aggressive or agitated, so keep your distance and don`t handle him unless necessary.

Why does neutering cause weight gain? In simple terms, neutering alters your pets hormonal balance, which can lead to their metabolism slowing down. This means that the calories they do consume are converted to energy more slowly, meaning they need to take in fewer of them.
Good quality kitten food is an excellent choice for weight gain in healthy cats. And most cats enjoy eating kitten food. Royal Canin Feline Health nutrition dry cat food for young kittens is nutrient- and calorie-dense and tends to be highly palatable to most cats.
Animal fats are the main source of energy for cats. “Good fats” is a term used to describe fats naturally present in meat and fish as well as the essential fatty acids such as Omega 3 and Omega 6 fatty acids. These “good fats” are fundamental to feline health.
As we said above it`s normal for cats to experience side effects such as lethargy, lack of appetite, nausea, and vomiting after being neutered, and you should call your vet if these symptoms don`t go away after 48 hours.
He no longer has the stress of needing to mark his territory and urinate throughout the house and yard. Neutered cats are also easier to get along with. They tend to more gentle and affectionate. Neutered males tend to roam less and typically are not involved in as many fights with other animals.
After your cat is neutered, it`s normal for them to experience side effects like lethargy, loss of appetite, nausea, and vomiting. You should contact your vet if these symptoms persist for more than 48 hours.
Benefits of Neutering (males):

Risk of testicular cancer is eliminated, and decreases incidence of prostate disease. Reduces number of unwanted cats/kittens/dogs/puppies. Decreases aggressive behavior, including dog bites. Helps dogs and cats live longer, healthier lives.

Many pets experience weight gain after they are spayed or neutered. This is true for both cats and dogs, girls and boys1. There are many causes of this, but some are related to hunger levels increasing in the absence of reproductive hormones1.
Eggs are not only a perfectly safe food source for cats – they offer much in the way of nutritional benefits. Aside from being rich in protein, eggs are also a great source of linoleic acid, Vitamin B2 and B12 and water-soluble Vitamin A – all of which are wonderful for your cat`s skin and coat.
Tuna alone is not an adequate meal that can provide a good balance of nutrients for your cat. In addition, tuna is high in mercury, which can lead to mercury poisoning in your cat despite being rare. Symptoms of mercury poisoning in cats include loss of coordination and balance, difficulty walking, and more.
Try keeping your cat awake longer.

Playing games with your cat, such as catch the laser pointer dot, fetch, and feather teasers can be very effective in tiring out willing cats. The longer you can keep your cat awake, the more likely they are to “crash” and sleep when you are.

Calming Cat Food and Cat Treats

Other options for managing stress include anti-anxiety diets, like the Royal Canin Veterinary Diet Calm formula dry cat food, and cat calming treats, like the Vetriscience Composure cat chews.

Most cats are actually `lactose intolerant` as they don`t have the enzyme (lactase) in their intestines to digest the sugar in milk (lactose), meaning that milk which contains lactose can make them poorly. They can get vomiting, diarrhoea and stomach pain from drinking it (just like lactose intolerance in humans).
It`s normal for cats to experience side effects as a result of the anesthesia and the procedure itself after being neutered such as discomfort, nausea, lethargy, and vomiting.
The age when a dog or cat is neutered often corresponds with a natural decrease in the pet`s growth rate and energy needs. Neutered animals also tend to consume more food and have a reduced basal metabolic rate — meaning they require less energy to keep the body functioning at rest.
While they may be groggy from the anesthesia post-op, spayed or neutered pets won`t know they`ve lost the ability to reproduce. They simply won`t feel the desire, or have the capacity, to do so.
Cats can often become more docile and affectionate after neutering. Even if they hadn`t displayed the redirected aggression mentioned above, there may have been some stress that was preventing your tomcat from being the gentle soul he could be.
A neutered male cat has had his testicles removed, not only ending his ability to reproduce but also removing his source of testosterone and his interest in hormone-driven behaviors. More than 90% will reduce this behavior with neutering.
If a male cat is neutered later in life, he`ll still have testosterone in his system that can induce sexual activity. It may take weeks or several months for the testosterone to leave the body.
When a cat is castrated, the testicles are removed but the scrotum (ball sack) isn`t. This means sometimes they look like they still have testicles after their operation. Over time the scrotum will shrink and become less noticeable.
Due to the anaesthetic, your cat may be sleepy and a bit unsteady for the next 12-24 hours and should be kept indoors. During this time she should be allowed to rest quietly in a warm (not too hot) comfortable place.
During a spay or neuter surgery, dogs and cats are fully anesthetized and feel no pain. Some animals may experience discomfort after the surgery. With pain management medication, they may not experience pain at all. Serious harm resulting from spaying or neutering surgery is extremely rare.
How Long Does It Take for a Cat To Recover From Being Neutered? For simple neuters, healing is usually 5-7 days. For abdominal surgery, healing is usually 10-14 days.

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. I have a cat that defecates in the litter box but always urinates outside the box. It is very annoying.
ANSWER : A. Inappropriate elimination in cats is often a behavioral problem rather than a medical problem, so the first step is to have him seen by your vet to eliminate any kind of illness or condition as a cause for his eliminating outside the box.

If medical issues are ruled out, take a look at other reasons. Has there been a lot of unusual activity? Has you cat been left at home or boarded? Is the litterbox in a busy area? Has anything happened recently in this area to make him reluctant to use it again? Is there another cat, pet or person that is preventing him from getting to the box? Have you changed it from a hooded to an open box, or vice versa? Is it big enough? Have you changed the type or brand of litter? Is there something attractive about the spot he uses? Cats dislike disturbances to their routine and may act out to express their dissatisfaction.

The general rule is one litter box per cat in the household, plus one. That way each cat can have a place of their own to go in case the box is occupied or another cat has claimed it as territory. They should be scooped daily, if not more often and changed completely weekly, washed with soap and water only. You can offer one kind of litter in one box and another kind in another to see if there is a preference. I don’t recommend the crystals, it makes a hissing sound when wet that startles some cats and make them reluctant to use it again. The litter boxes should be located in a quiet, low-traffic area so that the cat can use them in peace. Make sure any other pets or people aren’t giving them a hard time around or in the litter box. It may take some investigation and experimentation to find your cat’s preference and accommodate him so that everyone is satisfied with the situation. And, when cleaning up pet accidents, don’t use any cleaner containing ammonia. This leaves behind a scent similar to urine.

Q. My cat started to pee outside the litter box. What should I do?
ANSWER : A. Inappropriate bathroom use in cats is often a behavioral problem rather than a medical problem, so the first step is to have him seen by your vet to eliminate any kind of illness or condition as a cause for his defecating outside the box.

Once medical issues are ruled out, it’s time to take a look at other explanations. Has there been a lot of activity that wasn’t normal? Were you away and your cat was left at home or boarded? Is the litterbox located in a busy area? Has anything happened recently in this area to make him reluctant to use it again? Is there another cat, pet, or person that is preventing him from getting to the box? Have you changed it from a hooded to an open box, or vice versa? Have you changed the brand of litter or kind? Or is there something about the spot he has chosen to use that is attracting him in some way? Cats dislike disturbances to their routine and may act out as a way of expressing their dissatisfaction.

The general rule of thumb is one litter box per cat in the household, plus one. That way each cat can have a place of their own to go in case the box is occupied or another cat has claimed it as territory. They should be scooped at least daily, if not more often and changed completely on a weekly basis, and washed with soap and water.

You can also offer one kind of litter in one box and another kind in another to see if there is a preference. I don’t recommend the crystal kind, since it makes a hissing sound when wet that can startle some cats and make them reluctant to use it again.

The litter boxes should be located in a quiet, low-traffic area so that the cat can use them in peace. Make sure other pets or people aren’t giving them a hard time around or in the litterbox.

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.

Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation.
