Thank you all for your comments
Braingirl yes Ebony and rocket fuel has fast become a way of life in my house, sigh, I have my fingers firmly crossed that she will start to quieten down soon.
Hubby and I have spent the afternoon trying to work out how to sort this cage out. It was pointless just trying to fix this hole because she would obviously either just go back to it or move on to another place. So we came up with this idea.
We cut plywood to fit inside the base
We covered all 4 sides
Then we cut some thick doweling type wood and glued it into the corners to cover the joins
We purposefully made the wood higher than the plastic base thinking otherwise she may just sit and chew the top of the wood or even worse still manage to reach the plastic base sides over the wood. I was going to Plastikote the wood but Ebony is stressing in the bin, she has spent most of the day 'window washing' the bin sides, which sort of suggests a tank or bin probably won't work for her either. Anyway I want to get her back in her own cage and settled so I haven't got time to wait for paint to dry
Here it is finished with the top on and shelves in
Now I just need to move Ebony and all her belongings out of the bin and back into her cage and wait and see what happens next
