as scosha says, just keep an eye out for which corner they like to use and then put the litter tray there. unfortunately its easyer to put the tray where the bun wants to go than to try and make them go where you want them to go lol

the other thing is until you have them neautered you will get accidednts and litter training is gonna be hard. buns like to mark their territory with poo's and peeing which isnt very nice for us but generally reduces after neutering.
