Why did my calm cat suddenly get aggressive and poop at the vet?

Poor kitties can get so scared when going to the veterinarian. Some veterinarians are More comfortable with cranky cats than others. You may want to call you veterinarian and ask for a sedative to give her before you bring her in. This may be enough to allow the doctor to examine her well. If not, they may need to give her a little more sedation once she is there. I find that it is much less stressful to the kitty, and all involved if you use sedation in these circumstances. Best of luck and I hope she improves soon. Thank you for using Pet Coach.

That must have been very scary for you! Yes, I would be very concerned about Boo Bear attacking you viciously, especially if this is out of character for him. I'm not sure what his vaccination status is, but (not to scare you but to put the fact out there), sudden aggressiveness can be a sign of rabies. If he isn't vaccinated against rabies and is allowed to go outdoors, then I would be concerned rabies is a possibility. I would take him into a vet immediately if he isn't vaccinated and allowed outdoors, and you should see a doctor as well as soon as possible. Cats have a lot of nasty bacteria in their mouth, and you can get a terrible infection from the bite. You need to be on antibiotics now to prevent this. Other causes of his sudden aggression could be hormone related (I see he isn't neutered and he could be acting territorially), or a medical illness such as pain, an injury, or systemic illness. If he is up to date on his rabies and isn't allowed outside, then I would take him to the vet first thing in the morning. He should be examined by a vet to make sure there isn't a medical cause behind this sudden aggressive behavior. If it is hormone related, then I would have him neutered to help with that.

Neutering could definitely help the aggression problem. I would also recommend picking up a product called Feliway. It comes in a spray and a plug in and it has pheromones that can help calm your cat. You will not be able to smell it. Sometimes this helps, too. You can also spray the towel in the carrier so he can bring it with him to the vet. I would contact your vet for an oral medication to help sedate him prior to his next exam. This would help ensure his safety and every one that handles him.

If this is a recent behavior change for Cuddles, the first step would be to have him examined by a vet as soon as you are able to - there are a number of medical problems that can cause accidents outside the litter box, so your vet may recommend basic blood work and other testing to check for any evidence of a problem. If everything comes back normal, then it is likely that the issue is behavioral. Having accidents like this is often a stress or anxiety-related behavior in cats - if there have been any recent changes in the household, such as a new pet or a new baby, a move to a new house, or a guest staying with you, these could all be reasons for him to be pottying in inappropriate places. There may also be something about the litter box that he finds objectionable - he may not like the type of litter provided, or the location of the box. It can sometimes take some detective work to pinpoint the problem in cases like this, so if you're still stumped, I would consider making an appointment with a veterinary behaviorist - he/she can meet your cat in person and do an in-depth evaluation to help diagnose the problem and develop a plan to treat it. In the meantime, you can try a Feliway diffuser in the house or a natural calming supplement such as Composure to see if this helps.

I am sorry to hear about Memphis. Sometimes cats will react to a stressful situation by transferring their frustration/aggression to those nearby. I would be sure your kitty has a safe area at home where he feels like he can hide/get away if wanted and he can easily access his food/water/ and litterbox for the next few days. I would consider picking up a Feliway pheremone diffuser such as this one which releases pheremones which can be calming to anxious kitties. I would also consider a calming supplement such as Composure or Zylkene. Your vet may carry these or you can order them online or find them in some petstores https://www.petco.com/shop/en/petcostore/product/vetri-science-composure-feline-bite-sized-chews

Kittens are socialized through interaction with the mother cat and their littermates, and kittens who are separated from mom at a young age tend to miss out on this socialization. One explanation for why they may seem more aggressive is that they are treating people like other cats, and being more aggressive with them. I will also say that it is pretty common for cats to be fearful and therefore aggressive at the veterinary clinic - and who could blame them? Unpleasant things they don't understand tend to happen there. If she seems anxious and fearful at the vet you could ask about things to try to reduce her stress level like pheromones or a sedative.

The medications Tapatipo was given to sedate him may be causing the vomiting, but since I don't know what medication he was given, I can't say for certain. Certain anesthetic drugs can cause vomiting. I am concerned that he is vomiting but yet still appears to be sedated, and my worry is that he could aspirate on his vomit. To be safe, I would take him into a vet immediately to be checked out. Best of luck.
