I have tried them on my two cats. They last about two weeks at the most, then they have to be replaced. They look like they just had their nails done at a salon! My daughter had to put them on because it was too hard for me to see what I was doing. The glue dried up before I could use all the caps. You can order extra glue. I like them but also feel like it is a hassle to keep re-applying new ones. The cats take a little while to adjust and they try to chew them off. I'm glad I tried them but have stopped using them due to the fact that they are high maintenance. That is my personal experience, you & your cat may have a different experience. I would recommend you try them once and see. I wish they lasted longer, I might be inclined to use them again. Good Luck!
