Hey everybunny! i have been trying over the last week to start litter training little Spencer. I know he is very young so he won’t be perfect just yet but i just wanted to get some advice. 
At the moment the only lining in his cage is in his litter box and a old folded up shirt in a corner for him to sit on. I know it is best to have nothing other than the lining in the litter box but because he is so tiny and skinny i worry about him just laying on the cold hard floor.
He is doing pretty well with his poops but he still pees in one corner and sometimes on the shirt he ‘sleeps’ on. However when i take the shirt away he only sleeps in the litter box and then pees on the floor sometimes. I always clean up as soon as i see he has had an accident and then i leave a bit of it on the tissue in the litter box so he can smell it.
Is there anything else or different you suggest i should do?
Thanks!
