I have two 8-month-old kittens that we adopted at 10 weeks, male and female siblings. The first few times I tried, they both let me clip their nails. Since then, I managed to clip the female's nails a couple of times when she was asleep, and the male had his clipped at the vet. Lately though, they both will have none of it. They both struggle fiercely to get out of my arms. We've tried it with two people, used towels, but they are strong! I don't want to hurt them obviously or terrify them by trying too hard. I've tried handling their paws often, and tried treat rewards but that doesn't seem to be helping at all. I've watched videos on how to do it, but the cats in the videos always seem to be those that will hold still, albeit with some growling. Mine will just not hold still enough to even clip one nail. We are about ready to have the vet do it, but that is quite expensive and we'd rather not! Any suggestions?? I should add that they are both pretty friendly cats otherwise, and will tolerate being held at least for a short period of time.
