My cat, Annie, is three years old. She is usually a ver ya ffectionate and loving cat. However, her behaviour has changed drastically over the past week/week and a half. She is very agitated, growling and hissing at everything and everyone. And as well, she has taken to nipping fingers and toes. She is still eating and drinking normally.
I live in the country and she is an outdoor cat so she is exposed to all kinds of wildlife and we do have another cat, MC (it is actually Annie's daughter who is 2 1/2 yrs old). They have their usual tough and tougher spats once in a awhile, however Annie is ever attacking her for no reason whatsoever. Both cats are fixed and were at the vet 2 months ago so their shots are upt-to-date.
Please let me know if you have ever heard of anything like this and what if anything i can do for her.
