Bombay cats, when they are adults and done growing, are typically small cats.  An adult Bombay male weighs in at around 8 to 11 pounds.  Adult females, however, typically weighs between 6 and 9 pounds.

Bombay cats reach sexual maturity quickly, so if you don’t intend on breeding your cats, it is suggested that you spay and/or neuter your Bombay between the ages of 6 and 9 months.  Male Bombay’s have been known to sire litters at only 5 months old.

Physical development in Bombay’s is drastically slower, however.  For example, a male Bombay cat typically doesn’t reach his full muscular development until he is around 2 years old.
