Our guinea pigs are in an outdoor hutch (in a sheltered corner). We also have an outdoor run with a covered section which I try and get them out into for a run around every day. We've only had them a few weeks and recently the grass has stayed wet all day - is it still ok to put them out? If not, how is it best to give them exercise?
They aren't meant to, their bellies are low slung and not as protected as rabbits. But if the grass is damp and the ground isn't chilled, I've put our lardy adults out with a towel on a cardboard base (so they can sit comfy but still eat) if I want to clean the Pighouse without them getting underfoot.
They usually glare judgily and yell to go inside though
Oh no ChubbyPolecat DD would be devastated if that happened. I think I might pop a litter tray/plastic box with some hay in into the outdoor run for them (they're in the hutch at the moment but will pop them out for a bit when I get back in from work). Though as you say meglet they will blatantly just ignore the grass and huddle in the tray!
The only bits of mine that get exercise are their jaws, bowels and bladders Sadie did have her mad moments of racing round and round but she's now on the plump side and is as bone idle as Mollie now sigh
It took them a while to realise they could go in and out but now they do and the other day when I'd left them out and it tipped it down whilst I was out they were nice and cost until I returned them to their main hutch!
Today they are out and they go between being in the box and eating hay to going out and chomping on the grass. Another bonus is that it keeps their main hutch cleaner and the box is a doddle to clean out!
