The XS caps fit great for my 4 month old kitten. I would say a box would last about 2 months.

We bought these for my cat and the size has nothing to do will the opening and only how long the nails are. It was almost impossible to even get one on because of how small the opening for the nail is.

Okay so these are really cute, but very very difficult to use..at least for my cat. I thought they would be more pliable but they're not very bendy which makes them difficult to put on her nails. She is very skittish to begin with so I was a little hesitant as it was. If your cat is good with you clipping their nails, these will probably work great for you. I do enjoy the carrier that they come in; it keeps them organized and the clear ones separated from the colored ones.

I got the nail covers for my cat because my cat licks to scratch once specific chair. I was a little difficult to get them on at first but once you get it down it's easy to figure out. They're also pink, which is good.

I really like the idea of these but if you have a cat like I have they are a bit difficult to get on. Once we finally got them on the work well she did manage to get one off within a few hours though. My kid's really like that it looks like the cat's nails are painted.

I'm very surprised these work as well as they do. I've tried various versions of these products and they're amazing. They usually last about two to four weeks, and it will save your furniture. I will definitely be buying more of these in the future.

My cat seems to like them they were pretty easy to put on and now they’re not scratching the walls I gave my cat a treat why I was putting the nails on and my cat things and realize I was doing a nails and they don’t seem like they know they’re there

While the nail caps themselves are sturdy, attractive, and fit well on my cat's claws, the glue was a big problem. It was impossible to get out of the container--and, yes, I did cut off the tip. Because the container is such hard plastic, you really can't squeeze it the way you need to in order to get the glue to flow out and into the nail caps. I was able to get the caps onto my kitty, Dawson, only because I had some glue left over from another package of caps. I used that glue. Fortunately, Dawson is an extremely patient cat and didn't fuss while I tried over and over to use the official glue. Please fix this problem and this will be a great product all-around.
