Can pets (Dogs/Cats, etc..) have Mental Disorders/Illnesses?

Quick answer: depression and anxiety, not to my knowledge some of the same conditions humans have like schizo. Take Tizzy to the vet; she may need something added to or taken away from her diet. Is she exposed to toxins? Do you exercise her regularly? It seems she is "grading" the t.v.shows you watch. Good luck.
