If you only play Tabaxi characters in Dungeons and Dragons, does that mean you are a crazy cat lady?
The description of Tabaxi in Volo's Guide makes them similar to the Khajiit in Skyrim. They are not warlike Kzinti from Larry Niven's "Known Space" fictional universe. The description in Volo's Guide is vague enough to allow roll play a Tabaxi like either a Khajiit or a Kzinti. That was a tongue twister.
Dark Elf (Drow) and Lightfoot Halfling have the same stat modifiers as the Tabaxi. All three have plus two to dexterity and plus one to charisma.
You could argue the charisma to the Tabaxi it because they are cute.
Both the Drow and Tabaxi have darkvision; although the Drow can see 120' in the dark while the Tabaxi can only see 60'.
The Drow have the Dancing Lights cantrip and at higher levels the Faerie Fire and Darkness spells. Lightfoot Halflings have the advantage of luck. Tabaxi have Feline Agility, Cat's Claws, and Cat's Talent. Feline Agility gives the Tabaxi character the ability to move at double speed. Cat's Talent give the character proficiency in perception and stealth.
The Drow have sunlight sensitivity; Lightfoot Halflings can only move with a speed of 25. The Tabaxi have no documented disadvantages unlike the other two.
The Tabaxi have one significant advantage over any other race in Dungeons and Dragons. They are felines. That means the player can use all the cat videos on the Internet for inspiration on how to roll play their character. If a Tabaxi character likes another player character, does that mean they go out and kill a rodent and leave it beside the other player characters for them to find in the morning?
If the party finds a box or small chest, does the Tabaxi claim it for a sleeping place even though they can barely fit in it, with all their fur sticking out?
