Bit as apparently stopped...
(At least it's been a wile since she last chewed the wall.)
But I can tell you, nothing apparently worked
I just gave up... I tried everything you all suggested, the wall color was turning really strange

, and I just gave up for some days...
Then we went away on holidays for a week and left her at my sister's.
When we came back she never did it again...
By the way... even if she did it at my sister's, when she came back home she stopped peeing all over the house like before...
Now she uses the pad or does it outside...
She still as some "poop accidents" but not all the time...
She must have thought she was being abandoned for being "bad", the poor little thing, now she really tries to be "good"
Or maybe she's just older... but then she "grew" a lot in one single week...
I don't know... I don't care... I'm just really happy about it all...
