Litter box help/suggestions?
Hey there! So this isn't my first rodeo with some wobble kids but this is my first time having to deal with some litterbox help.
My two wobble cats (Bolt, black and white) and Champ (the big dude) share a box. Champ is quite large. When he pees he tends to just kind of crawl in, squat super low (almost laying) and pee. He doesn't really try to turn around, he has decided that the right side there is where he pees. He pees straight out of the back side which sometimes hits that corner and sometimes goes right out the opening. Poop is fine he goes in gets comfortable turns around makes a little nest. Bolt goes fine.
I've adjusted as much as I can. I have a rotating set of towels I use to catch any strays. Below the towel are puppy pads. There has to be a towel over the pads or else he just rips them up or pees on those directly. He is extremely particular about the condition of the litter box. If there's even one stray poop when he wants to go he just pees on the towel.
I'm wondering if anyone has any ideas. My apartment doesn't have washer dryer hookups so it gets pretty expensive washing the towels. If I wait till the end of the week I have to deal with the smell of the towels, if I wash them the day of incident I'm out $6 a day for one towel. To kind of manage I spray down some Natures Miracle and twice a week use a carpet spot scrubber to wash the area.
Quick note: They used to have 2 boxes. We had to relocate due to a fire in the apartment building and are living in a hotel for the time being. Everyone's ok and safe! This issue persisted even with the 2 boxes in their home. There isn't enough space in the room for a second box.
TLDR: big cat is able to go into the litter box but ends up peeing straight out of the door. Poop is fine, smaller cat is fine also
