Unicat is an esoteric programming language created in 2015 by User:Gemdude46.
The language is programmed using the 9 cat emoji: ( 😸 😹 😺 😻 😼 😽 😾 😿 🙀 ) All other characters are ignored.
Memory is an infinite tape of signed bignums.
A Unicat interpreter, as well as examples, can be found on Github.
Hello, world! is as follows:

A full documentation is yet to be written.
Any string is a valid Unicat program, although most will loop forever.
