Thank you Nancy
I honestly don't think it's at all possible for her to be able to get out of the cage in one night
going back to the beginning of this thread and checking the date she first ate a hole in the cage base, we added the wooden liner on exactly the same day, shows it was 12th October last year, today is 6th March, which means it has actually taken her just short of 5 months to get the wood that far
The lowest point of the wood was just level with the very uppermost point of the plastic base, which was still protected by the cage bars, so she still couldn't get to the plastic, yet, but it wouldn't have be long
which is why I had to reaccess the situation
Leaving the wood out failed miserably so I rebuilt it and replaced it
I assume it would take her a further 5 months before she gets near the base a second time
I was totally unaware that chewing wood could damage her teeth, I will take a look at the situation again and see if I can tweek it somehow
