I aasume then it was not the new lazer castration?
our vet groomed my male the day he was fixed,,, and he was out the cage and on his own in a few hours,, female aws 2 days,,, hes a long haired persian,, with fluffy tail,, he 's hard to keep clean, but i think if hes not bleeding and you are careful, use a wash cloth and no soap,, you should be ok,, just be cautiuous and let him decide if its ok or not,, he'll let ya know
