Does anyone have advice for a cat that eat grass? My cat seems to look forward to going outside to munch on some weeds in our garden that look like grass (long, thin strands) but every now it seems to mess up his poops and he'll scoot his butt around on the carpet. I'm wondering if there's a limit to how much he can have or if he just doesn't digest it right all the time. Also curious if anyone knows why he wants it so badly? He goes straight to it every day like he needs it
