When we picked up Trousers, her former owner gave us a big bag that had "food and hay" in it. We looked at the food today, and it is very clearly some sort of mixed crap for rabbits or guinea pigs (I can't remember what it's called, but when I had gerbils as a kid I fed them the gerbil version of this). In addition to the crappy food, it looks as though she went out into some fields and picked her own "hay" to give them. From everything I've read, this is a BIG no-no. I just want to know if there is anything we should look for as far as poisonous plants or grasses. We are NOT feeding it to any of our chins, but we know that Trousers ate some at her old home and we don't want her to get sick. Anything we should watch for?
