Kitten suddenly aggressive after shots and antibiotic......

[Foofyla]

I got a FVRCP vaccine for my 3 month old kitten last week as well as Clavamox for a minor wound he had. Now he is very aggressive towards my dogs, my other kittens - who are from the same litter as he is, and also bites my boyfriend and I. Could either the vaccine or the antibiotic cause this? I don't know what to do, any help would be greatly appreciated.

No, neither the vaccine nor the clavamox cause agression or what you are describing. I suspect there is something else that happened in the environment to cause the sudden change in behavior.

What was the wound, and how did it occur? If it was a bite wound from one of your other cats or the dogs, this would explain the sudden change in behavior. If by chance your dogs are terrorizing him, you need to train them to recognize what is off-limits in regards to your kittens/cats.
