So I have a problem. I have a cat who is behaving unpredictability - getting along well with my other animals and minutes (or seconds) later , hissing and attacking the same animal from across the room. This cat is 6 years old and has previously gotten along mostly well with all animals (a few spats, but this is distinct change). He had a checkup with a clean bill of health a few weeks ago (besides feline hypersthesia which he lives with) but I really feel like something is wrong. I'm afraid to leave my animals alone - I have two cats and a dog total and when one cat attacks it causes the other cat to attack and they either attack each other or both attack my dog, who doesn't fight back but could kill both cats if she wanted. It's scary and I'm hoping someone might have some ideas as to what could be wrong.
Thanks in advance for any ideas.
