Yesterday I brought my 6 yr old very docile cat into his new home to meet his new housemate where we will be moving permanantly next week. His housemate is a 4 yr old Tiger and very terratorial. To say the least the meeting did not go well. The resident cat went after my cat. When we tried to break it up, we were attacked. My cat is now in a safe room with all the necessities he needs, but is in hiding, not eating or peeing/pooping. Any suggestions for a reintroduction or to help my cat get over the trauma?
