What size were you trying to feed with originally? Just curious, lots of people say different things lol. Also congrats! So happy for you and your Mr.Beans! I hope it stays this way!

It might also have been the change from rat to mice that got him to eat- many BPs have preferences. But...it's done now, water under the bridge.
