It sounds mean, but teaching them to sort of “give in” to the select medication/grooming windows is important. It’s actually not bad that bribing with food doesn’t work because when owners become dependent on that, they run into difficulty when it no longer works!

Whatever method you use, make sure you are committed and follow through. I recommend doing the same routine in terms of visual/location cues as well, so it’s clear when it’s “Game on, time to do this” vs. you just interacting normally.

I recommend picking up or solid floor for medication– cushiony surfaces are unstable (imagine walking on a mattress) and can make it more difficult to have a secure hold and this the rabbit feels less secure too.
