Most people here are going to say don't declaw. I am opposed to declawing. While Soft Claws are more work & less permanent, they work just fine. They do not have the "effects" that declawing can have(litter box issues later in life, the pain of the actual decalw surgery, nippiness, etc.). I used them on Lily, my kitten for a few months, & I now no longer use them. I check her claws once a week & if they need to be cliped, I clip them. Plus, she looked so cute in them!
I had no trouble putting them on the first time & no trouble putting on new ones as they fell off. I did it myself everytime. I ordered straight from the website & I figured out how much it cost. I paid $60 for 120 nail caps, estimating those nail caps would last Lily 6 months. By then, I guessed that I wouldn't need them anymore. It costs more than $60 to have a cat declawed(unless you do it at the time of spay/neuter), so the nail caps were cheaper. I tell people that all of the time. Really, I only used one package on Lily, the other two were on fosters & Ophelia.
I now use Soft Claws on Ophelia, my semi-feral housecat. While it wasn't fun to put them on her, I had no trouble replacing the ones that fell off.
