To clarify I don't let my cat go outside and he sometimes runs around the house and has several hiding spots I don't know to this day. However my cat occasionally gets a wound (Usually near his head). He recovers on his own and doesn't seem disturbed by the wound in the slightest (He does get disturbed when I try to get a good angle on the wound to properly see it.) But I'm worried that there may be some sort of numbing issue near his head which worries me.
Should I be worried or is it normal for cats to not to be disturbed by their wounds?
