Liquid piss smells like fish. I hate it and all mine do it about every 2 weeks without Urates or Crap. Tonight I had sophie out and I seen her tail go up so i ran over with the Tub and put her over it... She went about 1/4 cup liquid... Couldnt of played out better. Thats why when I hear newbies talking about wood ViV's i tell them its just now possible unles they PVC the inside and silicone all seams.. Put 90 degrees to a Fishy Smelling wood and see how fast you clear out your house hahahahahah
