Thanks for the tips... I decided to go for the litter tray, got one last night and filled it with fresh hay.. They loved it ! They jumped in it and did most of their wee in there overnight.. Just washed it all out and put fresh hay in, prob need to put paper or something in the bottom to soak up the wee throughout the day thou.. They had completely moved it from where I left it last night ! Hay bags sounds like a good idea too, will have to look how to make one of those. The fleece that was covered in wet wee hay has washed ok but would not have one so soaked again.. Might make a mini cage liner for the bottom of the litter tray same as their cage liners .. Has anyone used those puppy training pads? Was thinking of using those and cutting to size just for the bottom of it maybe?
