It’s empty in here!
I ran out a couple of months ago but reordered this week. I took the tube out of the box and as I was unsealing it I'm not sure if it was the sound or if there was a smell that they could detect, but I had cats coming running and begging like they don't do for any other type of treat, not even the best advertised treats on the market. We also noticed a big reduction in hairballs when we feed this. We use all Smilla products and their coats are very glossy and they are full of energy.
