Why don't you just contribute a little to the electricity bill?
You'll be paying for the cost of prey anyway...so a few quid extra a month won't hurt...and it will show your parents you're responsible. Plus you'll be able to keep what you want, rather than something...anything...just because it's not going to cost your parents to heat it.
