Well, I went and bought some and have a look. Aren't they purty? They do work well but have a couple of drawbacks. Firstly, the info sheet says to cut their nails every 6 to 8 weeks. I don't know about everyone else but Huck's nails need to be cut at least every couple of weeks. Secondly, cutting the nails without actually being able to see the nails is a bit tricky and makes me nervous. And lastly, while they work on not scratching the floors, etc. they don't come off very easily. They've been on for almost a month so far and he's lost all but three. I purposely cut the tips off so they would fall off (according to the info sheet) but the last three are still hanging in there. So anyway, just thought I'd follow up on the product.
