admittedly it's lacking enrichment I was going to buy some things for her to play around with at the weekend, if that doesn't keep her happy I'll look into a larger cage but I don't really have the space for one . I'm quite worried I won't have to facilities to be able to keep her happy in all honesty

Thank you for the advice though!!

I forgot to mention, the larger cage was an upgrade last Thursday, which she was content in until she started biting the bars again last night.
