Maybe my kitten is accident prone, but she got another nail cap stuck in the carpet last night. This time, she sat there and did not panic. She meowed at me like "Hey, I'm stuck again". I used a pair of scissors to cut her from the carpet.
NailBlue nail cap over claw with red string caught at base
It's very possible I bought a size too large. My kitten is only 4.8 pounds now and I probably should have bought the kitten size. I had purchased and used the small size at the end of January. Also, it was the first time I applied the nail caps. I may not have put them on correctly.
Overall, I think the product is a good alternative to declawing. There are still 2 nail caps on my kitten as of date. I plan to wait until she grows a little more before applying another set.
I shoud probably note that my kitten got her sharp claw (no nail cap) stuck on her sisal scratching post too. So, I've concluded that soft claws are probably no more dangerous than her own sharpened claws.
