Hello everyone. I just joined following an advice from a caring person who read my ad on craigslist. I do apologize for a long post, but I feel like I need to explain everything from the beginning. I currently have 3 cats. One 10 year old female, One 7y.o male and a 1 year old male. The 7 y.o we took in after our neighbors abandoned him when they moved out. He was accepted by our older female cat. But a little over a year ago we saved a newborn kitten, nursed him, raised him. He had many issues when he was a baby, was constantly hospitalized. He grew into a big cat, but became extremely aggressive towards the 7yo cat. We tried everything. Went to vets, neutered him, got calming collars and diffusers. Nothing is working. The poor 7yo cat is afraid to walk around the house. He started loosing fur because of stress. He is scared to even go to his litter box. I literally have to hand feed him and carry him around. Im barely home due to heavy work schedule. I am at the point that I need to give him away. But looking to see if there are any other options. I can not separate them into different rooms. Please advise.
