Originally the decision was made for me not to have more (OH is allergic) but I really don't know how I've coped with 3 this long. Had I been able to get a fourth so I could have two pairs or a quad I would've been okay with that but three singles is not ideal. I love each of them in their own way. They are fantastic to relate to individually. But with three cats and two dogs (and we used to have two bigger dogs when Mimzy first came home) it's too much. I can't give equal attention to each animal and I feel bad when any of them are shorted.
Three separate bunny habitats are a nightmare to upkeep as well. They can't be free range in our place and that's nothing short of tragic. I would've loved to have seen them all zooming about and flopping wherever they pleased.
I do feel that although they are cared for and comfortable they are not enjoying the best they could have, so in that respect I have failed them.
