Have Cat Questions? Ask a Cat Vet Online.
Thanks so much for requesting me. I am happy to help someone as wonderful as you!
Can you please give me some more info so I get a better picture of Rupert?
Have you had him all ten years of his life?
How long is he biting and scratching you?
is he eating and eliminating normally?
is he an indoor kitty?
any other pets or new things in his life?
any known health issues?
Please mention anything new no mater how small you think it may be.
After your reply please give me a few minutes to type detailed answer.
thanks I bought himfrom the vet and he has been an inside cat ever since.He has always scratched a bit even from being a kitten but I thought he would grow out of it. There has been no changes to his life. The vet says he's healthy and he eats well but often vomits some food,which he's done from kittenhood
Thanks so much for your helpful reply.I apologize, I was off line when you replied last night.
When a normally sweet kitty becomes aggressive he is usually dealing with pain or discomfort. However, you say Rupert has always been a scratcher.
Feel all over his body and look in his mouth for a stuck item or any abnormalities.
If you do not find anything, Rupert may have a touch of kitty dementia.
Hyperthyroid is another disease of older cats that can cause aggression:
Of course, Rupert may just be getting a bit insecure and just wants your attention.
This is NOT a mean or aggressive cat. He just becomes overstimulated.
This is the way cats act when they play with other cats -they have a specific language they use to communicate with each other.
The trick is to watch his body language and stop petting the instant you see his tail swish or his ears go back.
I had a similar problem with one of mine.
I put a stop to it by teaching him he will NEVER get my attention if he uses his teeth or claws. He can only get petting when he approaches me calmly and quietly.
NEVER SPRAY WATER! That is a definite NONO! It actually causes more aggression. Just say NO! and turn your back. You do not want to give any attention, even negative. Just ignore him. You can clap your hands or shake a can of coins.
When he comes to you quietly you must immediately give him a treat so he knows he did the right thing. Once he realizes he will only get attention when he is calm, he will change his behavior.
You can also get him a feliway collar or plug-in to keep him calm:http://www.amazon.com/GOODbehavior-Pheromone-Calming-Collar-Cat/dp/B0026JAKWG
some of his behavior can be caused by boredom so put our foraging and interactive toys to appeal to his hunting instincts.
Rupert needs more exercise so play with him to tire him out.
Please let me know how things go. If you still have questions just press reply and I will always be here for you.
Warmest best wishes,
