The buns' grandparents bought me a food dehydrator earlier this year, so I bought some cranberries to dry out for bunny treats. (Both Calvin and Jessica love Oxbow's Critter Berries, a tableted form of herbs and stuff flavored with cranberries.)
On a whim, I decided to see if they liked plain cranberries before I went to the trouble of dehydrating them and finding out they didn't like them. (I know there are "Craisins," but they are sugared and, well, the buns don't need a sugar buzz.)
Calvin took a whiff at one cranberry and ate it right up. Jess hasn't eaten a whole one, but she's eaten half of one that Calvin had dropped. (They're a two-bite treat, I guess.) Calvin won't eat more than two or three at a time, but he does like them.
I had hoped to see what a rabbit "sour" face looked like, something like what a kid looks like after tasting real lemon for the first time, but he made no particular face at all. Dill after mint, and now plain cranberries without sugar. Remind me not to eat anything they prepare for dinner! :-)
