now i don't think he even uses it it at all...cause eh goes out a lot...my concern is today it's been raining so he's been in all day...I seen him a couple times walk up to the litter box, look at it and then walk away...I thinking he wants to use it...? idk...can a cat become so used to going outside that they don't use the litter box anymore....if he really needs to go...why doesn't he just use the litter box...or is him stopping and looking at the litter box just some random thing????
