My buns love most fruits and veggies. Someone on the forum said that Craisins are like bunny crack. They are not kidding. I give my buns a treat when they come out of their cage in the afternoon or evening, usually Craisins. I just moved into my new apartment and I give them their treats on the floor in the living room, next to the couch. Today, I let them out and then went to the bathroom. When I came out, they were both standing next to the couch waiting for me impatiently. As soon as I got close to them, they surrounded me. Two bunnies surrounded me. They started periscoping as soon as I had the bag of Craisins in my hand. They know the routine. I also give them greens. Their favorite, which is also nice and inexpensive, is cilantro. They go just as crazy for that as for Craisins. Anyway, as ILuvMyLilBuns said, wait a few weeks until they are old enough for treats. In the meantime, and after, give them toys. I found my boys love bird toys. My son, who lives with his dad now, has a bird, so we started with a couple toys he didn't like and they loved them. So, we found other bird toys they might like. They have been spoiled buns. I miss Freddy (the bird) already. Cardboard boxes are also a favorite. Bugsy and Groucho have not objected to all the moving boxes all over the apartment.
