The wooden/paper based cat litter is the best kind. We keep our two ladies on the same. However, I'd be cautious about 3 males together as they'll likely fight. |
Fresh fruit and veg is the best treat you can go for. Much better for them than any shop bought 'chewy sticks'.
Make sure they have plenty of stuff to climb on, ours have branches to piss about on.
Can't help with the tricks.
