I have more pin pricks just above my knees. I can pick up Girlcat & sit her on my knees, then after a while she decides to jump down & pushes off with her back legs; cue little claw punctures from over-long back claws.
They definitely need doing, but it takes at least 3 hands - one to hold her firmly, one to hold the relevant paw, one to wield the clippers. I know some people will say you can hold the cat and the paw with one hand together, but she wriggles so to get away I just can't manage. Hoping my DSis & nephew will be able to come & give me a hand this weekend.
