At the cost, these are probably a great incentive for certain individuals. I needed to check whether my pet rabbit would appreciate it, yet he is by all accounts careful about it and not set one paw on it for a couple of days. Then after a week he started to crawl on top of it and seem to enjoy the grass. I also have pet mice and I will try to put some artificial grass in their habitat and see if they will shred it to dust in a matter of hours! haha! but overall, this grass is a great value and useful to my pets.
