Cat5

I do believe it is some sot of CAT

I can't see really, the photo is too blurry and low resolution.

The connector looks like a fully populated RJ45 connector, making me draw a conclude that the cable is some kind of category network cable.

CAT-10. The other one has the first 9.

CatV (V for void)

Blue

Ethercat

Cat 4

CAT1

Whatever kind of cable it is, it belongs to the cat now.

Looks like standard Cat-5 ethernet for home use.

Cat Infinity

Whiskernet

(this joke makes more sense if you owned an early-gen Kindle)

USB-Cat

That looks like telephony cable to me. With googly eyes added on. So life-like!

Ethernet with built-in netcat

the cat could choke sir
