Hope this is OK to post - sometimes the pests are living right under our noses!
Yeah, I grew up with cats, my mom grew up growing and repotting aloe vera. Only my last cat decided she actually likes to nom them. Figured out that they were toxic when I went on holiday and brought my cat over to them. She came back with a swollen mouth and chin. Aloe has been banished, every single plant got googled and cat-approved (or thrown out/banished to outside).
