I have a cat and she is 8 years old. For the past week she has been in hideout mode. It started to scare me when my whole family hasn't seen her downstairs to eat,drink,or use the kitty litter. For a day we were forcing water down her. She would eat, but not drink or use the kitty liter. Now she eats and drinks and goes into the kitty litter if forced and the bathroom door is shut. She acts petrified when she is downstairs with her eyes wide and constantly edgy. When shes up stairs in her hiding spots she licks your hand, she plays with a string and when held purrs. I called the vet and a nurse said it sounds like a mental problem. It was no real threat since she is eating and drinking. I have 2 other cats. one for 4 years and a new one for 3 1/2 months. I don't think its the other cats bc she isnt aggressive towards either one especially the new kitten and she gives her kisses sometimes. HELP if this has happend to you or advice!
