I've used Tigerino for years and loved it and when I discovered the multicat version, it was even better. Worked well, odour gone, I was very happy. But unfortunately the last few bags I purchased were so dusty that my cat has now constant sneezing fits. I thought I'd buy the sensitive version then. That was even worse, I start szeezing now when I scoop it in the morning. I'm sad about it, but I don't know what's happened to the supplier. Not good any more,I'm afraid, I'll have to change brand.
