The surgery will be less traumatic and the feline will recover. If you wait until they are adults it will be much harder on the bobby's feet. Do not consider defanging them. If you want to reduce a bobcat's natural inclination to spray, you need to spay or neuter before it reaches adulthood. This surgery will eliminate much, but definitely not all, spray behavior.
Bobcats can be affectionate, entertaining, and demanding.
They live ten to twenty years in captivity and do not transfer very well to new owners once they are adults. Think carefully about any decision to adopt a bobcat kitten. Good luck and call with any questions.
