I don’t know where you are but I have seen many House Rabbit Society webpages has a list of rabbit sitters. Is there an HRS close to you? If they don’t have a list on their website maybe you can email them and ask what they suggest? Or email a local bunny rescue- I know some of them offer this as a service.
Does anyone on here live close to you?
I have heard people leaving buns at those dog retreats when gone for a longer period of time. But I think my buns would freak out and be upset the entire time w/ the strange place and barking dogs.
I always get the cold shoulder when we come back from being gone. I am lucky that my inlaws love the buns (the only grandkids they have for now) so we have bunnysitters when needed.
The biggest fear is that if something happened, like your bun stops eating or pooping, there needs to be someone to catch it. And I agree w/ above-my buns would eat ALL their food in one sitting and have nothing left for the rest of the time.
