I do that. I love it too, it's my favorite part. But I would say that that is a SMALL portion of what I do with the bunnies. 1-3 times a week I clean cages, groom, ect.
Yesterday I spent over 2 hours cleaning all the cages, washing bunny dishes, tidying the rabbitry, giving health checks, grooming and nail clipping to some of the bunnies. On Wednesday I'll clip the rest of the bunnies' nails, as well as give health checks and groom.
Do I enjoy doing all of this? Not really. But it is so rewarding to see all my hard work pay off. Live litters of babies couldn't occur without clean conditions. Growing, healthy rabbits couldn't be without a clean environment. What's the point of breeding rabbits, having/raising rabbits, if they aren't happy?
