To help out with removing Smokey's treats, I planted a planter full of organic cat grass, in organic soil. After it grew nicely I brought it in for him to be able to munch on when he wants (he doesn't seem to throw it up...regular grass he does). I just saw him looking at it, and poking his nose in it. It's covered in little green bugs! I'm assuming it's just aphids, and assuming they won't hurt him. But thought I'd check. I've put it outside, and cleaned the entire area. I ussually treat my plants for aphids, and other bugs...but smokey doesn't touch them, and he's kept inside for at least 3 days after anything has been treated. (Treatment says pet safe...but we like to be safer yet). Won't use anything on something I expect he'll eat!
