Do you have a cat? Or a small dog?
If your bunny is that.... Uhm... rough... I would suggest practicing the burrito.
There is a real technique to doing the burrito properly. Meaning tight enough and fast enough. A properly burritoed bunny (or angry cat) should not be able to move. Quick enough that by the time the animal has realised whats happening, youre done.
It can be difficult to do it quick enough however if youre not used to it
so sometimes practicing on less angry animals helps lol
Have the rabbit sitting or laying on a towel. The nose and bum of the rabbit should be facing the long end of the towel.
You may be best positioned kneeling slightly above the rabbit (off the towel) at the rabbits hind end.
There should be enough towel at the front of the rabbit so you can do the next step. Think of the towel around the neck portion as a neck brace. So you want enough towel up there.
Bring the front edge of the towel up and around the rabbits neck.
Bring one side of the towel and fairly snugly tuck it under the rabbit. Keeping the portion around the neck snug.
Do the exact same thing with the other side of the towel. SNUG.
Your bunny (or other critter) should be a super snug sausage. Don't worry about the back end as your body should be here preventing rear end escapes, and if you've done the neck portion snug enough, they shouldn't be able to back out anyway.
A proper Burrito is snug enough to prevent movement, but not so snug as to strangle. They have much smaller necks under all that hair then we think. So youre usually pretty safe to go quite snug.
This should give you full control of the head of the rabbit, even when the rabbit is not being backed by your body. They should not be able to move their head around to bite.
You can use a fairly firm grasp on the head with out hurting them.
