My baby-cat poops once in 2 days ever since I switched from wet & dry to dry only. Seems she does drink more water with dry-only but now she stopped pooping every day.
When she was fed with wet & dry, her poo poo got kinda loose & stinky.
My vet told me to cut down on wet to prevent that. I dunno which is better for her, though...
Just FYI, she is on Hill's prescription s/d.
