Okay, that’s horrible! They are putting so much stress on the rabbits. And rabbits can get heart attacks SUPER easily.
1. They are in a new environment they are not familiar with REPEATEDLY. In a small cage with nowhere to go.
2. Most likely people will do this for their kids so they can see what having a rabbit is like. Those kids could very easily kill the rabbits or very easily scar them for life by picking them up wrong, dropping them, grabbing them very sternly...
3. One of my rabbits that I owned at one time got a heart attack from my dog just running into the room. Think of how much worse ‘rent a bunny’ could do to those poor rabbits. ☹
I just don’t see any benefit.
