Indoor bunny owners - radiators

I know it's supposed to be Summer but I'm thinking about Winter already :lol: How do you block off your radiators when they're on? Do you have proper covers and where did you get them? What ever I use it can't be too big as it will block a walkway. My two sit under the radiator all the time, they chin it, lick it and try to nibble it sometimes too :roll:

i don't, but then I don't put there's on too high. Half of it is covered with a pen panel so they can sit near it.

I don't really have my radiator on in the bunny room. To be honest even if I did I don't think they'd go near it?

Mine love sitting under the radiator when it's on!
I just have it on low and I brought plastic covers to go over the hot pipes.
