Mine do this (but only in their indoor cage) . They are ver' ver' judgey at being in a small space (this is from the guineas who will condense themselves into one segment of their Bookcase Tunnel- basically a 3 section bookcase with doors cut into the 'walls' to give them a hidey space)
Mine will reward my care by leaving a puddle of pee and some random droppings (I blame my DDs tricolours , my pig wouldn't do that sort of thing )
Ours are quite good at letting us know they want to pee when we cuddle them. But are yours moulting? DD and I end up like Yetis after 5 minutes
one of ours does exactly that. The other squawks and squawks in a monotone way which sounds suspiciously like whining!!
piggies are funny things. Ours regularly try it on and pretend they've not had veg.
If I feed them They drag it all into their hidies and when DH comes past they squawk like they've not been fed and are being neglected. So for the last three days running our crafty piggies have had two breakfasts and at least one extra dinner!
