What do you think of....
1) Rajah - princess Jasmine's tiger bodyguard.
2) Ramesses - greatest pharoh of Egypt. Since he does look like one of those Egyptian cats and is so huge and regal looking.
3) Ozymandias - a sonnet written about Ramesses. He could go by Ozzy for short.
4) Bagheera - mowgli's panther friend, is still an option.
Any other suggestions?
