Supposedly this cat food reduces allergens by 47% via a Fel d 1 binding protein. Not sure how much of it is marketing but I notice a slight decrease in my allergies after giving this to my cat, YMMV.
Delivery for this item is free to most metro and major regional areas.
I started my cat on this 2 months ago after I had suddenly become allergic to him after 2 years of getting him. I can say it works although it's hard to gauge. My allergies do still trigger every now and then. Thanks for the deal OP, grabbin a bag.
