Cats Claws are very small

I have this kitten vet claimed she was about 6  to 8 months  I had her spayed  and is doing good But I have this concern for her shes has extremly very  very small claws and the do not appear to be growing what so ever in fact they have even growled back when the vet clipped the tips of them from sergery and that has been about a month ago I called my vets and they had nothing anybody ever have this problem ?

Some cats claws simply grow faster or slower than others. I trim the claws of all (or most) of the cats at the shelter where I volunteer. Kittens sometimes need a trim once a week. The adult cats vary. Most of them I do every other week but there are always one or two who don't need it more than once every 3 or 4 weeks. My own cats are the same way. Sometimes I can't keep track of who needs a trim.

I wouldn't worry about it unless she seems to be having other problems like not walking right or showing signs of pain.
