I'm hoping someone can help me. My cat is seriously depressed. We've had her for about 6 years. The year after we got her, we got another cat (that was abandoned). Well, the 2nd cat got pregnant and had 2 kittens that we kept. This was 2 years ago. Ever since then, my original cat has been depressed beyond words. She doesn't play anymore and just kind of hides all the time. She cut down on her food intake, too. She's still eating, but not enough and she's lost a lot of weight. She's also been drooling a bit.
Just recently, she's started to NOT use the cat box. She will poop next to it, but will not use it. Then, last night, she peed in my bed. Needless to say, I was NOT happy.
She's never been outside, so I don't think she picked up anything and all the other cats are totally healthy.
What could be the problem here? Is it just her being depressed or do you think it's something more?
