I have a couple rabbits and I was wondering if was safe to take them to the park. There they like to nibble on tree bark and grass (and some weeds and/or clover). I believe the trees are maple (but not 100% sure). Apparently the parks aren’t sprayed with any chemicals because one of the park representatives said that if there wasn’t a little white sign on the grass or in the area that no chemicals have been sprayed. They’ve nibbled on outside vegetation/bark a few times and they seem fine. I was just wondering if it would be safe for continued occasional (2-4 X per week) exposure. Thanks.
