My oldest, the sole survivor from a threesome of brothers, has never been on his own before, and he seems to be amusing himself in ways that perhaps his brothers didn't allow! He kept putting his dishes (still full) into his plastic tunnel and I'd also hear an awful lot of banging going on at times, then yesterday, stuck at home in the snow, i saw what he was actually doing and it's not something I've seen before, he is catching hold of the front of his plastic hide with his teeth and whilst still inside lifting it up, walking forward, putting it over the dish and then pulling it back with the dish in it. I was stunned because (dont' throw me off the forum but I've always found the guineas to be the least intelligent of the rodents I have kept, they are certainly not in the same league as rodents such as rats, who are def more intelligent than most humans I meet) I can't work out whether it took him ages to work out how to do it, as it is most certainly totally deliberate, or why he is doing it now as there is no one else in the cage who might eat the food. Bless him, he at least took my mind off being snowed in!
