Mickey is going to the vet today (with Lucas and Amber who get shots) so the vet can look in his mouth. I noticed the gums on one side are really red but the other side is fine. I know that he is in the process of losing is baby teeth (found 2 canines on the floor recently), but I do not know if it is happening properly or if he has a problem (I have't had many kittens at his age, most of mine were adopted older).
I say to him "Oh yeah! Now that I adopted you, you go and have expensive dental problems!" And then he nuzzles me and I melt into a puddle.
I'll let you know after we return from the vet's what we find out.
