Both my kitties use Soft Paws - Otis has the cutest blue toes, and Jazz looks very regal in her purple ones; their toes have become part of their identity (and its really funny when people meet them for the first time from a distance and ask "Did you paint your cats' claws... Obviously they've never tried to hold n excited kitty down

). I've had Jazz one month now and have just had to replace the first one - the kit says they stay on 4-6 weeks, which is probably pretty accurate, and there's 40 toes in one kit... You do glue them on - there's two tubes of adhesive which come with the kit; you put the glue in, then stick the toes over the kitties claws... Neither one of my cats like the application process, but neither like having their paws touched either so I don't think its the result of the product. Otis has been wearing them for a year and tolerates in pretty well now, once i catch him to do it Once they're on, they seem to groom their feet for a couple of minutes and forget they're there. I think Softpaws are a wonderful thing - both my babies use a scratching post pretty good, but they do forget every now and then... Also, no hurting each other or mom when they play rough, and when they decide to go on their wild rampages through the house at 3 in the morning, mom doesn't need to worry as much about whether her furniture is okay...
