RE: Holding down a cat:
An easy, friendly way to hold a cat so that you don't get shredded during care is to toss a quillt over their back, as they are unsuspecting, then wrap them up in your arms and hold them like a baby. you can hold them with one hand and give care with the other. Have all your supplies on a table beforehand, so you can easily grab them with your one hand. Eventually your cat will know that when you do this he/she does not need to be scared. My cat no longer needs to be wrapped up when I cut her nails. She growls quietly, but is never violent.
