My cat is angry after vet visit. Will his behavior return to normal?

Hi there! It can often take several days for cats to fully calm down and return to normal after a stressful event, so I would tend to agree with your vet - it's likely that he just needs more time. You can try using a Feliway pheromone diffuser to help him relax, or a natural calming supplement such as Composure or Zylkene to see if this helps.

I think your kitty is upset with you and thinks you abandoned him at the vet. Leave him alone for a day or two, feed him his very favorite food and start petting him gently while he eats. He will come around and eventually like you again. Obviously he is very attached to you or he would not be so grumpy now. I think you might ask around and find out from other cat owners which vet they recommend, as Maddy may not be happy to go to your present vet. This does not mean your vet is a bad vet, just that Maddy might not like him. Give him lots of TLC when he lets you again and all will be well.

Cats are very temperamental creatures and can be thrown out of balance by small changes in their environment. Sometimes these changes are imperceptible to us humans, while others the cause may be something more obvious (the addition of another person or animal, moving to a new location, change of diet, etc). Based on what you are telling me he sounds very stable and overall overtly healthy. I understand it is difficult to get a hold of him, but another reason for him to be acting abnormally would be if he is in some measure of discomfort or pain. I would suggest ruling this out with your vet, and once this is done, begin trying to produce an environment that is as enriching and stress-free as possible for Jhumru. I would not push him too much in an attempt to regain his affection. Allow him to come back into his own and come to you when he is ready. Obviously, if the doctor is able to find something physically to explain this behavior, ideally resolving this issue will also resolve the behavior change. Hope this helps.

Your cat is most likely reacting to the "trauma" of going to the veterinarian, rather than the vaccinations. This is not an uncommon reaction for some cats. She may be shy or skittish around you for a day or two post-vet trip but should start to calm down if you leave her alone and give her space to recover on her own. (Some cats do take a little longer.) As long as she is still eating, drinking, and using the litter box appropriately (both urine and feces), then she should be fine in time. However, if she stops eating or drinking or using the litter box, you need to contact your veterinarian.

It sounds like poor Pook has been through a lot lately! Give him time, he will trust you again. Leave out his favorite treats near where you are sitting, and he will come to get them. When he lets you pet him, praise him and give him more treats. He should settle down eventually.

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

There does seem to be an unusual phenomenon that when one animal attends the vet for a time its companion can react badly on its return. Possibly due to unfamiliar smells. Usually it settles after a week or so. If not you could try bathing the cat or invest in a pheromone diffuser to try and settle them.
