Hi! First post! I found this forum while looking for info on glue that can be used for Soft Claws.
I have two sibling kittens, a girl and a boy, about 9 months old. I've been using Soft Claws with both of them for about 2 and a half months or so. They're great!
The original poster asked if they can be reused. They can... if you can find the old shed ones... I've found more or less half of them.
When the nail sheaths shed and fall off along with the soft claw covers, the sheath will still be glued tightly to the soft claw, which would make it difficult to reuse. But if you soak them in nail polish remover, you can get them clean enough to reuse. (That's why I was looking alternative glues -- I ran out of glue cos I'm reusing them!)
Before soaking them in nail polish remover, it helps to squeeze them to break up the hard glue and any glued on sheath material. Roll them round in your fingers or use a small pliers or tweazer. After doing this, you'll be able to pull out pieces of sheath and glue. It's kind of fun, actually. Then soak them in nail polish for about 20 to 30 minutes.
After soaking, you should be able to use the tweazer to lift out whatever material remains inside or around the rim of the soft claw cover. There's often a build up of gunk around the rim that can also be wiped away after a soaking. I've used nail polish remover with acetone; I don't know if non-acetone remover will work.
After soaking, the soft claw cover will be very soft, more so, I think, than an unused one. But after a while they stiffen up again -- it's possible the polish remover breaks down the plastic slightly. I'm not sure. But I've reused a few paws-worth of covers at least once, and it works great.
I'd like to find a non-toxic glue to use, although what's non-toxic for a human might not be for a much smaller animal.
I put soft claws on all the claws on the front AND rear paws of both cats. They're not crazy about the process of clipping and putting on the covers. But they don't seem to mind at all that they're on. In fact, except for the first moment or so after I apply them, they don't seem to even notice that they're there.
As someone already noted, the coverings don't interfere with their ability to retract or extend their claws, since they cover only the tips, and are nowhere near the joint. My cats still scratch on their scratching posts, and anywhere else they feel like, so it doesn't interfere with their need to scratch.
At first I noticed that they have a little less traction, like when they're running fast in circles (e.g., chasing a toy) but they accommodated themselves to that right away.
I've been handling their paws a few times every day, to get them used to it. And each soft paws session has been easier than the one before. I usually wait until they each need a few replacements and do a bunch at a time. I'm not certain, but I *think* that some of the covers from the first session, nearly three months ago, are still on... some look like they're ready to fall off, but are still holding on. I'm gonna try to keep better track of which ones I replace, just for fun.
I used to keep a collar on one of the kittens so I could tell them apart -- they're nearly identical -- but now I just rely on their differrent colored tosies... and their emerging different personalities!
I was skeptical about Soft Claws at first, but became an instant believer. I got them because I like to play with my cats but don't like getting scratched. I wish I had discovered soft claws years ago for my two previous cats. I'd have far fewer scars on my arms and legs!
lots of great advice here........although the photos of the scratches were a little freaky 
..........I suppose I will just have to have a go..............get him wrapped up well in a towel, have hubby poised with the pre-glued nails.......then..............well .............see how it goes eh 
.......well theres no chance of a 2nd go !! 
you know how cats can be 
but since I have no intention of putting Soft Paws on Oz when he doesn't need them, how will this effect their play-fighting?
But I think a lot of cats get used to not hurting furniture, people, etc. with them on so don't be surprised if he shreds something once off. For example, I dont' reprimand Anya for stretching on our furniture now since she wears them and I know she's not hurting anything. Should she all of a sudden not wear them she would still stretch and scratch...only with disastrous results. 
She scratches on the right things for the most part, and leaves our stuff and the woodwork alone now. Occasionally we have to reprimand her (sometimes she gets excited and wants to get Mike's speakers). But mostly she's fine.
I don't know how she did it, but she 
So we didn't have to do a lot of training.
