I just found this formula online from a successful rescue friend. It's called Wombaroo, and it is especially formulated for rabbits, which is hard to do with current formulas, goats milk and such. I havent gotten to try it yet because it came in the mail too late after I lost my last one. I had been hand feeding 2 litters from someone who brought them to me after finding their butchered does were actually pregnant and due to deliver in the next day or 2. I was surprised that they lasted a whole week on what I was giving, but in the end, it just wasn't working and they all either died of starvation cause they wouldn't take the formula, or bloat. I havent decided if I'm up for trying again or not. It was exhausting and heartbreaking in the end.
