So Loki has really been enjoying his new cage! Thank you all for your replies, I am glad i can share it somewhere!
I also added mealworms as a treat into his diet and OMG he went crazy. I never saw him this quick.
This is a photo afterwards - it is like "mom, more veggies? I want more worms I am a dangerous worm hunter!!!"
Here he is watching tv series with me
And lastly this is his furious attack on paper tissues after getting his house cleaned
I was quite worried because I noticed a tiny red spot on his paw, but it seems OK today, I will keep checking.
