Thread: Not finishing in the tray...........?

Sounds like he is constipated.

Is the tray placed in a low traffic / private area for them? Is it big enough for him? Does it have a lid?

How old is he? Maybe the varied diet is too complex for him to get used to? Maybe he'd do better just with one kind of dry food and access to plenty of water? Maybe he'd be better just on a wet food? So many variables and imponderables.

If you can't keep him clean with a simple wipe and a comb through then I'd trim his butt and breaches.
