Background

Sialic acid-binding immunoglobulin-like lectins (Siglecs) are cell surface receptors of the I-type lectin family that are expressed on innate immune cells and bind to sialylated and non-sialylated ligands. Myelin-Associated Glycoprotein (MAG), also known as Siglec-4a, is a type I transmembrane glycoprotein belonging to the Siglec family, a subgroup of the Ig superfamily. It is selectively expressed by myelinating cells including Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS). It is encoded by a single gene that is conserved among vertebrates. It is composed of an extracellular segment containing five Ig-like domains, a single transmembrane segment, and a cytoplasmic domain. Mature MAG exists as two isoforms, termed S-MAG (short) and L-MAG (long), due to alternative splicing of the cytoplasmic domain.

Fun for my puff ball lover
Size: 30 Pcs
The gun is very cheaply made and sometimes shoots when the trigger isn't pulled. But my puff ball loving monster seems to love it and all his new puff balls. He was literally jumping with joy.

What a great cat toy!
Size: 100 Pcs
So I bought two of these. One for me and the house cat and one for my niece and her garage/indoor cat. My cat is nearing her 16th year in the world and loves attacking these balls…when she is in the mood and not sleepy. They are great to throw at her, as she will bat at them or catch and bite them. They are super light weight and will not hurt the cat even when triggered by the gun. The gun will launch the ball a good yard or so, but it’s much more interesting if you angle it up and towards the cat as they will watch and attack as it falls. I have tried endlessly to make a video but she stops every time I hit record. It’s not just with this toy but with anything I try and catch her doing…hit record and she is suddenly on her best behavior or walks away. :/ I recommend this product for bored household cats and I think even the young ones would have more fun with it. I should mention that the gun noise might be a bit jarring to cats, but if you put a small hair tie (like the small clear ties) around the back pull- piece (this is the piece you pull back to cock the gun and put a soft ball in the chamber) it mutes the sound of the gun being fired. Overall, the cat and I are happy with this product.

It's funny but cheap
My cat does enjoy chasing the little fluff balls around and then batting them for a few seconds than looking back at me for more. It's good for some good laughs and entertainment but the fluff balls and little plastic shooter are honestly dollar tree level quality. The shooter has one flimsy spring and looking at the placement inside it seems like something that'll fall apart pretty fast. Not worth $11 or $8, this should be >$5 easily.
