I already did something like that - I put some of his used bedding from the cardboard box in the litter box to begin with, so he'd recognize his own smell. Then I put some of the poops in it while he was watching so he'd get the idea that poops belong in the litter box.Flash is a cute name. I was going to suggest putting all his poops into the litter box and then lure him back in. Glad to hear he is peeing in there as I am sure you are too.
Whatever type of cage you get it is best if they can enter and exit on their own. It is less stressful for them and you.
Our first cage was the kind that you had to lift bunny in or out unless you took the whole top off. We had to roll up our 5X7 area rug everytime we needed to get Lucky back in. When he ran out of rug he finally allowed us to pick him up to go back in.
He gets parsley as part of his daily greens, but I think it's his least favorite. I wasn't going to buy more when I run out, since there are so many other veggies he hasn't tried yet that I want to offer him instead. Carrot's the only fresh veggie he likes enough to specifically look for, though as I said, he's getting bored with it. I haven't tried fresh bananas with him yet. I have some, but I usually eat them when I'm at work, not home, so it's tough to share.What about fresh banana pieces. They are a bit slimy and hard to handle but my bunners love banana.
And I have heard some buns go crazy for parsley. Maybe he would go for parsley?
