Thanks Eeji, hadn't picked up on the fact that feeding hadn't been dealt with properly . A medium mouse can go for anything from 35p to 60p, from below that price to above that price . It all depends on where you buy them. You can buy in bulk, which makes it cheaper but isn't easy to do when you've only got one snake and you don't know how long he'll be on mediums for. Some online shops are RS Reptile Supplies , Premier Exotics and A & N Frozen Reptile Food . Or it's a case of buying from your nearest Pets at Home, pet shop or reptile shop.
Glad you've got them ready Jakob. Might be worth waiting for at least a day after you've fitted the stat before you feed him, to give him a chance to settle down after his viv has been disturbed. That way you can also be 100% sure that the temp is where you want it to be. Hope the thermostat arrives soon.
