I noticed that all 3 of my cats
were sneezing more frequently after the new box of litter. The other 2 cats
got over it and I returned the product. Cloud was not so lucky. He probably did have an infection because he started to eat less and even passed on his favorite shrimp... After Convenia sneezing stopped in 48 hours, there was no running nose. My joy did not last. On the third day Cloud became lethargic, hardly ate. On the fourth day he did not eat or drink but secluded himself.
