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 Bengal cat is a considerably older breed than the others in this list, but as a breed derived from a wild cat hybrid, it is worth a look. The Bengal breed, which developed from a cross between a domestic cat and an Asian leopard Cat, is also the starting point for other breeds in this list. There have been stories of naturally occurring crossbreeds in Asia from way back, with the oldest confirmed case in 1934. The breed as we know it began with geneticist Jean Sugden-Mills, who crossed ALCs with domestic cats in 1963. Twenty years of breeding resulted in the breed that was accepted as truly domestic by TICA. Bengal cats are large cats with distinctive markings. Generations F4 and beyond are considered to be good house pets.
