Since I have an xpen for Sammy’s habitat, I just climb in there with her and sit down on the floor. I kind of upend the hiding baskets, so she hasn’t got far to go. Then I leave her on the floor also, but set her between my theighs so she’s kind of securely held with my legs, facing away from me. I firmly place one hand to hold her behind her ears, pressing against her shoulders. That spot indicates dominance to them, and she’ll hold still for one paw at least. She often runs away after the first paw, but resigns herself with the other.
For the back feet she allows me to lift her and lean her back against my chest, holding her around her stomach firmly. Her back feet stick out that way. If she struggles even a little bit, I let her go Immediately! The harm to a bunny’s delicate back is in a fall or wrenching around. They are much safer if you let go.
A bunny burrito is a great way to do it, and a friend holding her in one is best, so you can use both hands for the trim. Be sure to give her a treat when it’s over, so she can eventually learn that it will be coming once this regular ordeal is over.
(And I think Sammy also learned that her feetsies feel better after a trim, so she ultimately likes it when its over.)
