https://www.dictionary.com/e/slang/furries/
Furries are fans of anthropomorphic animals. These are animals with human characteristics, like Mickey Mouse, Sonic the Hedgehog, and many mascots for sports teams. Furries are part of the greater furry fandom. Besides referring to fans of anthropomorphic characters, furries are also the anthro characters themselves.

There was quite a build-up before the word furry was first used in reference to fans of anthropomorphic (anthro for short) characters. Fans of Steve Gallacci, an artist who drew anthro characters, came together at a sci-fi convention called Noreascon II (part of the World Science Fiction Convention) in 1980. This led to informal gatherings centered around anthro characters in sci-fi, comics, and animation between 1980 to 1985.

After the initial rallying together of fans, online bulletin boards started taking off in 1983, uniting furries across the globe. Though it’s not known exactly when the term furry was first used, the term furry party was used at Westercon, a “science fantasy” convention, in 1986. This led to the fandom being known as the furry fandom later in the decade. The first ever furry convention was held not long after that in 1989. This was ConFurence 0, the first of many furry conventions.

This is “questions about SCRATCH”. Go on another forum platform to ask this.

But to answer your question, it's just a person in a suit that's like an animal, known as a “fursuit”.

They are quite controversial.
