My cat was attacked by a coyote. Is his new aggressive behavior PTSD?

Since she was gone for so long, an examine with your veterinarian would be recommended. This may diagnose any underlying injury or infection. Frequently, either can be responsible for a sudden change in behavior. In the meantime, give her space and time to reacclimate to you. Don't force her to be held or pet. Offer treats and praise when she comes close. A pheromone product, such as Feliway Spray or plug in diffuser, may help to decrease any anxiety.

Poor Sebastian. He could be scared or traumatized from being outside. He may have gotten into a fight while being on his own and he could be hurt. Sometimes when vets are hurt they will be skoddosh because they don't want people touching them. If there is a way a trap him and take him to the vet for an exam, you may want to do that. Just be careful to not get bit. Also you could try to offer him some cat food and treats and see if you can regain his trust. I hope he starts to come around for you.

I think it is normal behavior for a cat that just got wrangled out from under a deck. Cats really hate to be forced to do anything and when they get in that hyper-excitable state, they tend to be grumpy for a while. Give her a little space for about 30 minutes and see if she calms down. Sometimes it takes a day or two, before they return to normal. If she continues to be abnormally grumpy for longer than 30 minutes, then I would be concerned that she may be hurt. Check her for any obvious injuries and if you find anything concerning, then it's best to have her checked by a vet.

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

The first thing I would do for now is put Attila in a room by herself with a litter box, food and water bowls, comfortable resting places, etc. and leave her alone for the next few days apart from coming in briefly to refill her food and water and change her litter. When cats become upset and aggressive like this, for whatever reason, it can take up to a week for them to fully calm down and return to normal - until then, it's best to leave her completely alone and give her plenty of space. Some cats can have serious aggression issues that are triggered by a strange or scary noise, an unusual smell, or anything else that startles them. It's possible that Attila may have had a scary dream that frightened her, or she could be painful due to a pinched nerve, arthritis, or some other issue that may have been aggravated by petting. If she calms down over the next few days and things return to normal with no further problems, you may not need to do anything else. If she is still acting aggressive a week from now, or if this becomes a recurring problem for her in the future, I would strongly recommend making an appointment with a veterinary behaviorist - he/she can evaluate Attila in person and help you determine what may be triggering these episodes, and will also give you some specific suggestions for managing her when this happens. Prescription medication is helpful for some cats with aggression issues, so this is something that could be discussed also.

Hello. Your cat may have experienced some minor trauma or even an unpleasant event outside. I have seen cats chased by dogs & even dive bombed by angry jays that would come into the house & sulk. And you never rule out some medical reason like a fever. If your cat continues to act strangely or unwell, refuses to eat or drink, please have him examined by your veterinarian as soon as convenient.

Thanks for using Petco Pet Education Center, formerly Petcoach! If she just came back home I would just give her some time to readjust. Sometimes with time they go back to their typical behavior. If no improvement, I would check with your veterinarian if she is on any medications as this could be due to her reacting to a medication. If she is not on any medications and she does not improve, I would also check in with your veterinarian to make sure that she is not acting like this due to discomfort. Good luck and have a great day!
