I just got mine today in the mail, and already applied on Lucky and Hope - I am debating if I am going to apply on Bugsy - probably so, but not 100% sure yet.
I needed to put it on Hope because she uses her claws a lot for anything she does - kneading, playing, eating, whatever!
I have a lot of scratches from her, and so do the kitties.
Lucky I got because she scratches the carpet too much, and I rent, so I don't want to damage.
Bugsy is pretty good with his claws, scratching on the proper place, etc; he also uses his claws to climb the cat tree, instead of jumping... Since this is a great exercise, I am going to hold a little on him...
Anyway - VERY easy to put on... easier than clipping their nails - much easier than clipping the nails... I clipped their nails the day before, to not traumatize them too much, and today I applied the SC. Following the instruction, I filled all claws with glue at once, before starting to apply them. The whole process probably took a couple of minutes...
Very Very easy, and I LOVE not being scratched by little hope!
Hope doesn't even notice it at all! Lucky has been trying to take them off, but they are holding on pretty well... I think it is just the time for her to get used to them.
