Yesterday I went and bought my two house bunnies a litter tray each, my newest bunny Cherry (Female) she had a litter tray at the pet shop so took to it straight away, but Chance (Male) won't use it first he moved it and peed and poo'd where it was so I attached it to the cage so because he couldn't move it he went into another corner, he's not done as yet also I don't know his background as he was found roaming around, he's very much like a child, he had a temper tantrum with the potty because it was there, anyone have any ideas?
