I think I hurt her tooth!

OMG! I think I just hurt Zoe! She was playing with her rabbit-fur toy all ferocious and then she attacked my foot. She bit my toe (I wasn't paying attention) and surprised me, so I quickly jerked my foot away. There was a loud SNAP! noise. I checked my sock and there isn't a hole, so surely it was her tooth! I feel so bad! She is kind of moving her jaw around as if she is sucking on where I hurt her. I checked her mouth and all of her baby teeth (she's only 11 wks) are still in place. But now she's not playing so I fear I hurt her bad! Oh I feel like an AWFUL meowmy! She is just laying down in my lap, semi-napping.... Her teeth are still there, and they aren't loose, but surely I hurt her!

I don't think it sounds like you hurt her bad. Hope she will turn out fine.

If all her teeth are there, but she's acting a little "off", then it might be good to get her into the vet in case it was her jaw that made the loud snap.
Everything might be ok, but a good "just in case" measure would be a good thing I think.

Hugs to you and your little girl.

I also agree with tru if she still seems bothered by her mouth a vet check could be needed. Although its not likely that its broke but its better to check just even to calm your fears.
