Apparently, we don't meet the criteria for suitable adopters from our local bunny rescue. 
I don't know whether I'm more annoyed or amused!
DH is definitely annoyed... he wanted to do the right thing and get a suitable pair who need a new home, rather than exacerbating, in a small way, the trade for baby bunnies.
I've barely talked him down from sending a very arsey email attaching all the approvals we gained for him to adopt my older children recently.
