Well... We DO have a huge bucket but it was used for the dog for 1 month. Then it was dusty and used for washing clothes. And yeah the breathing issue. Still can't spell it right. That sounds like a very good idea but the hole is too big and the mud problem is there. Rain = mud/ Mud + pond = R.I.P. I realized that the liner was a waste and will put the bucket there instead. But the mud thing is there AND there s the danger that those two stray cats sassy and black Kim might go for a little snack. And our cat too.
