My mother's beautiful Himalayan cat [8 years old now] has been transferred from home to home since my mother's death 3 years ago. She has moved 6 times in 3 years but was always well cared for. However, she has developed a bad attitude, hissing and swatting at anyone who comes near, growling when you walk in the room and swatting at your feet when you walk by. My husband and I now have her and she has a room all to herself for the most part...she has been with us for over a week and seemed on the road to adjustment at first but each time visitors come by we have to start all over with calming her down again. Should we just leave her alone and hope for the best? Should we shut her in a room alone - if so, for how long? Is there a medication we can give her to keep her from being so stressed out when people come and to speed up her adjustment? I feel terrible at the thought of medicating her but she gets almost crazy with running away and hissing...it's clear she is very stressed out and has become almost wild and uncontrollable. I've had to take a spray bottle to her twice when she went after a visitor so I wondered if medicating her when we know people are coming over will help? She stays in a closed room but even so seems a bit crazed even when things are quiet again.
Poor thing! She is certainly stressed out. Keep her in one room only. One that is NOT active. I rescued a very abused Himmie. She stayed in that room for 3 months. I would visit her every chance I got. She eventually realized this was her home, and I was her new owner. I would sit with her, and pet and soothe her. The minute she acted up, I left the room. She eventually caught on, that when she was nice, I stayed. She wanted the attention, so she behaved nicely for longer and longer. Same with her combing sessions. Eventually I left the door open and she was free to roam. But that was always her "safe" haven. I would omit having guests meet her. Keep her safe in her "safe" room. She will eventually venture out. She feels abandoned, and several times over. You can try a mild sedative from the vet as well. My Himalyan has been with me for nine years now. She is not a pleasant cat to guests. She only like my dad, because he feeds her the "good stuff" from the table. Other than that, she hisses at everyone. So when friends come over, I leave her be where she is hiding. Give your kittie time, it will come around, but it could take a long, long time. I hope this is the end of her being shipped around, as it might just get even more confused and angrier at being abandoned.
I had a cat named Uriah. He was strictly an indoor cat but I think he had a little Ferrell in him. Anyways, when he got to be about 7 years old he started hissing and swatting for no apparent reason. My vet prescribed Chlorpromazine which is a mild sedative. It did wonders. You can get it in solid or liquid.
Another thing to consider is that if this came about suddenly there may be an underlining medical condition associated with it. Maybe he's in pain or something.
