You must be so excited to get your little boy, remember the feeling well
We have two litter tray's for two Bengal's, some people say that it's a good idea to have a litter tray for each cat and then a spare one, we have never needed the third one, we have one down stair's and one up the stairs, they tend to use the down the stairs one during the day and the up stairs one during the night, also, why don't you try getting an enclosed litter tray? trust me, they are great, when we first got our two, we had just the normal open litter tray's, but Troy was getting litter everywhere
I mean everywhere, he seemed to take a freaky when covering his mess, he's very particular about that and likes to make sure the job is done right
all we seemed to do was hover up litter
since getting the enclosed litter tray's, well, we will never again go back to the open one's, we always lift the poo's straight after they have done them, but sometime's if you are out and come back, well, there is no smell, great for holding the odour's in too
