His collar can make him invisible. It was shown in "The Grass is Always Meaner" towards the end of the episode. He achieved it by repairing some parts of collar However, this power soon disappeared once Kat got the collar wet by falling in Old Lady Munson's birdbath. It's possible that Kat is still able to restore it.
Kat's collar also has a built-in communication device and listening transmitter that lets him contact other Kats and communicate with them; this was first seen in the episode "Do Not Fort Sake Me" where Kat had only the communicator but not the listening transmitter. The listening transmitter was not seen until the episode "Stall That Jazz" where Kat got it lodged in his ear while communicating with a fellow Catnipian.
The collar has a detachable clip on it that holds portrates of Kat's Family.
