Last week I woke up in the night to find Misha had chewed and scratched a large part of plaster & paint of the wall on the stairs. We told her off, she sulked for a day or two and has ignored it since. This is the first time she has chewed anything she shouldn't. Just turned round from the pc and she was there, licking the wall again. She knew it was wrong, big guilty face - I've sent her to her bed. Any ideas how I can stop her? I've read about bitter apple spray but I haven't seen it in Spain and obviously I can't move the wall out of the way. Is there anything else readily available I can put onto the wall? Also, I can't imagine plaster is good to eat, but is it a sign she is missing something in her diet, or is she being a pup?
