Thank you all for your replies. My parents have all given consent to handle them and feed them so I can't see it would be a problem. I only have a small house and space is rather limited so the cage is going to take up some space lol but they do need to come in as it's getting colder. Yes I will risk assess and ensure no droppings have come out of cage and food, straw and sawdust etc.
I know a lot if nursery a have guinea pigs or rabbits indoors.
