KITTY LITTER HELP

Amy • Just a girl

Okay so I have 4 cats. One 15 yrs one 3yrs one 2yrs and one 6mo. (Also three dogs). As you can imagine, kitty litter is very important in my house, but it gets EVERYWHERE! They will kick it out and track it all over the house. I’m looking for some help here. I’ve tried covered litter boxes and litter mats but the cover did nothing and my 15 yr old cat pees on the mat. Please any suggestions???
