I really like the new litter but I have noticed in both the darker and lighter version of the litter (Jonny Cat comes in a lighter and darker clay) the wet clay looks overall darker after she urinates than her old litter(freshstep). She is on perpetual clavamox antibiotic for her medical conditions so I don't think she has an infection, she is eating good, drinking good and peeing good. It might just be the change of clay type so I have some left over older litter that she used to be on and will switch back to see if there is a difference. We see her vet this week anyhow so we will see. I decided to put a double layer of white paper towel under the litter in her litter box to see if I can see the color as the urine migrates to the bottom. I tried it on one box that needed changing and will change the other tomorrow. She is a little backed off from eating today but that happens on and off with her inflammatory bowel disease and whether or not she has had a bowel movement. Has anyone had this experience?
