An increase in respiratory rate may be an indicator of pain especially if she is limping; without examining Isabella I cannot say whether this is due to pain or another cause (infection, heart disease etc…). I would restrict Isabella’s movements and monitor her for the time being but if it continues or the respiratory rate is above 40 breaths per minute you should visit your Veterinarian for an examination.

The AZA (American Zoological Association) zoos got together and took captive bred ocelots and released them in TX. The problem was that none of the cats in zoos had come from TX originally because the ocelots in TX had been extinct for a long time. Instead, they had all come from cats who were taken from the wilds of Central America long ago. In Central America ocelots eat snakes because most of them are non venomous. When the zoo bred ocelots were turned loose in TX they reverted to their ancient instincts in search of food and sought out snakes, but the TX snakes were mostly rattlesnakes and the ocelot program died out in a matter of weeks.
