Background

Human interferon alpha-2 (IFNα2) is a cytokine belonging to the family of type I IFNs. IFNα2 is a protein secreted by cells infected by a virus and acting on other cells to inhibit viral infection.IFNα2 was the first subtype to be characterized in the early eighties. As a result, IFNα2 was widely used in basic research to elucidate biological activities, structure and mechanism of action of type I IFNs. IFNα2 was also the first IFN to be produced by the pharmaceutical industry for use as a drug.In addition to their antiviral activity, type I IFNs also inhibit the proliferation of cells and regulate the activation of the immune system.

Really indestructible
Color: Yellow
As advertised. I have an obsessed 16lb mixed breed dog that has destroyed everything purchased that says indestructible. Until now... These balls really are indestructible. She loves them and plays with 2-3 at a time. Chews on them and still going. They are the size of regular tennis balls. Others are slightly smaller. These are great and bright... Mooky highly recommends.

A Dog’s REAL Best Friend!
Color: White, Color: White
This ball is truly my dog’s best friend! It is perfect especially for indoor fetch because it’s lightweight (AKA nondestructive!), has just the right amount of bounce, and cannot be torn up by mild to medium chewers. (We have a labradoodle and she isn’t much of a chewer.) It really is bite resistant, and I have a video to prove it! Our dog loves the softness of it. We love that we can throw it around the house without it breaking anything. It almost feels like heavy duty bouncy styrofoam that cannot be picked at or bitten up. We bought the pack and are storing a couple of them for when we someday lose them here and there. I recommend this ball to EVERYone who has a dog and likes to play fetch! FOFOS, pick us for ads! My doggie is obsessed with your product, and I love taking pics and videos of her using it. She’s the type of dog that walks around with a ball in her mouth for fun and comfort. Think of it as her stuffed animal.

Never pop balls
Color: White
These things are the best balls you can buy. My dog loves playing with them and chewing on them. And she has never popped one they are a great purchase if your dog usually pops other balls. These are solid and light weight
