I was cleaning the litter boxes just now and of course my cat decided that was the perfect time to pee, LOL. I waited until he was done and scooped the clump out of the box. However it wasn't a normal clump. His urine was foamy and sorta sticky? Could this be because I use arm & hammer litter deodorant or should I take him to the vet? The brand of litter is super scoop, he's eating and drinking water normally.
