Google "soft paws" and check out the product. I'm not affiliated in any way, but I did use them on my cats. Once you get the hang of putting them on properly they work quite well. They can be used several times, too. . .you'll find them around the house (provided you get a fun, colored set rather than clear) and just glue them back on, provided that not too much of the nail sheath (the part that they naturally shed) comes off with it.

OH - and did I mention that the cats cry during the surgery? The anesthesia knocks them out but doesn't totally deaden the sensation - it truly is awful. I'm so glad the UK outlawed declawing, docking (of tails) and cropping (of ears); the latter two are equally horrid surgeries.
