Hey folks, new member here so I hope I've posted this in the right place!

I recently purchased my first ever Ball Python (several months old) about 2 weeks ago from an established and trusted breeder in my local area (I am in the UK). Unfortunately I am having trouble getting her to eat.

I also own two Corn Snakes but they have never given me any trouble with eating so this is a new experience for me.

My new BP (Coyah I have named her) was due a feed the day after I got her so the breeder gave me a frozen fuzzy rat home with me. The next day I defrosted the rat and set it on the heat mat for a short while to warm it up. When I offered the rat to Coyah she immediately took it and constricted it. Then she got her mouth round the head of the rat and appeared to be starting to eat it. After a few minutes though she stopped and just left the rat sitting there. I left it in overnight but it was still there in the morning.

So last night (a week later) I tried again but this time she would only sniff the rat and wouldn't even go for it. This morning the rat is still there.

It's two weeks now since I got her so I'm thinking she should be more or less settled in. Any ideas as to why she won't eat?

I had a 3ft vivarium ready for her when I brought her home but the breeder advised me that if I put her in the 3ft viv she wouldn't feed so I put her in one of those Exo Terra faunariums. She has lignocel substrate with heat mat under half of the faunarium and a cork bark hide. I can't really fit much into the faunarium but feel she is maybe feeling too exposed? Could I move her into the 3ft viv if I had loads of stuff in there to give her more cover and security?Advice much appreciated!
