Or are they specifically made for front feet only?
I trim Cola's claws but she scratches and it HURTS! Especially her back claws! She tends to jump on people and dig in with her back feet to get her balance.

So can we put them on her back feet?

I used Soft Paws (if thats what you mean) for a short while and in the faq section of their website they say it is okay to put them on back legs.

It's just usually harder to get your kitty to let you do it.

Thanks for the link! :)
