Erps been getting some bad knots this summer, first time in her 6 years. I have clippers here but they are for me, I am assuming that cat clippers and human clippers arent the same and I shouldnt use the human clippers on Erp, is this correct?

Erp is a very trusting and forgiving cat so I have no problem using the clippers on her by myself, I just dont want to use my clippers if they will hurt her.
