We have two piggies who have lived outside since we got them about a month ago. It's getting cold and I had assumed I'd just get an insulating cover when the time came, but today I've looked at Pets at Home and the insulating cover is £67 plus it needs a waterproof cover which was another £40 -ish. I really didn't realise how expensive it would be.
If there isn't another way, I'll just have to swallow the cost, but I wonder if there's something else I can do? DD1 would like us to get an indoor hutch, but I'm yet to be convinced.
