Allergy
Unfortunately, I have discovered after several purchases that my cat can’t tolerate Iams food, as she has been licking and pulling out large patches of fur from her skin for quite some time. I thought it was something in the environment causing it, that she was stressed or understimulated. It wasn’t until I switched to allergy food that she stopped and her fur became thick again. I don’t know what it was in the food that she was allergic to, but this is just a heads-up to other cat owners that the food can make a difference.
