2 of my cats appear to have lost their minds. Leo started whining and crying last night. I thought I had corrected the problem by giving him back his favorite water bowl. I went to pet him earlier today and he got agitated and looked like he was about to jump at me when I touched him. Georgia is usually very sweet, but she has bitten me 3 times today after she insisted on being held. She bit me while I was holding her and then jumped down and bit my foot. This happened twice. There are no changes in the house, no new people, no undue stress. Leo is currently whining while laying in his usual spot on the floor. The only new thing is the water bowl. If Leo doesn't quit by tomorrow, he is going to the vet.
