We have recently adopted a 4 year old F4 male Savannah who just will NOT use his litter box consistently. He urinates in it 100% of the time but when he goes to use #2 it's a hit or miss. Sometimes it's in the box sometimes it's in the floor. We have switched litter brands, we even bought the cat attract brand, we have brought in a second litter box, we have moved them around. NOTHING. He has been here at the house for 4 months. Note we do have 3 other male cats who have SEPARATE boxes than the new male. They aren't getting along well YET, that is also a work in progress. Any tips or suggestions would be appreciated.
