Just wondering if it is normal for kittens to have a medium brown colored buildup in the ears? (Not deep, just inside.) Teeka has a little bit, but I've really noticed that our new kitten Raisins has it badly. Both kittens were at the vets for various reasons, but nothing was ever said - nor was it cleaned.
What is this? Should we clean it, or take them to the vet to have it done?
Our older cat Moo doesn't have this, and I don't recall ever dealing or seeing this with her.
