What animal doesn't pee and poop?
All animals need to pee and poop. Birds are not able to separate their pee and poop, their feces are mixed.
To answer your question frogs do poop (trust me I've seen the left overs on my garage door.) but if they pee I've never seen a frog pee but i think that they do. Frogs actually do pee. The waste filtered from their blood becomes urine, which passes from the kidney to the bladder and then out of the body.
