I was wondering....1) what is the difference between a mash, and a collection of chopped vegetables that you have cooked/steamed, and 2) where do you place your perches so your small birds don't poop in their bowls while they're eating? Risa's (BHP) bowl is a big ceramic one, so she steps from the perch on to the bowl, and bends into the bowl to get the food, then turns around, still standing on the bowl, and eats. She poops in her bowls sometimes that way. There aren't any perches above her bowls so she can't be pooping from above. Any suggestions? Thanks.
