Baby teeth?

Mew is 4 months old, and is apparently loosing baby teeth!? I was just checking her teeth (i guess for tartar/boredom), and she has 2 canine teeth on one side and 1 on the other. This had me curious, and when I looked closer i could see that the back one was loose!
Is it normal to teethe this early? Where are her teeth going? And are there any possible issues i need to look out for? Thank you!

*wasnt sure where to post this! Sorry!

At four months of age, she's right on time for getting her adult teeth, and often kittens do have two canine teeth in at the same time.  The loose one is the baby tooth which should fall out shortly.  Here is a link  to a very detailed article about cats teething if you want to know more.

Thank you for the info! I had previously read that teething was coming, and have been checking her mouth at least once a week. However, I wasn't expecting her to lose them until 6 months or so. That explains her rank breath! :lol3: I was worried that her swallowing them would do some damage inside, ya know? I guess she is fine, and doesn't even act like her mouth hurts (other than bringing her stuffed mouse EVERYWHERE). She is currently running laps around the house, and playing tag with her toys!
