Hi Lau
I had my feral family in the shed, adults until they were neutered and rehomed on a farm and the kittens were in there until a couple of weeks ago. I already had lights and a couple of plug sockets (plus the shed had its own fuse box!!) I bought an oil filled radiator from argos for 20 quid and just had that plugged in. It kept the shed warm enough through the snow and everything. I had a rug down over the concrete floor and had beds, scratch posts, toys, radio etc in there. It was really good for taming the kittens as they were away from the hustle and bustle of the house. They are doing so well they have now made it into the house and have a new set up in the spare room. I let them out for short periods each day and you would hardly believe they used to be feral

Good luck with getting them set up

P.s. I did take my dyson down the shed and hoover up the cobwebs and grass cuttings...my neighbours must have thought I was mad lol!
