Here's an update that adds new ocelot and void cat fur options, as well as versions of the DnD 5E tabaxi racial bonuses.
The "Feline Agility" ability should work the same as the tabletop version, giving tabaxi a free dash that's available at the start of combat and after any turn where they don't move. The "Cat's Claws" bonus in tabletop converts tabaxis' 1d4 bashing unarmed damage to 1d6 slashing- unfortunately, it doesn't currently seem to be possible to convert unarmed damage to slashing in the BG3 engine, so the mod's version just adds 2 slashing damage to all unarmed attacks. Once the official modding tools are released, I'll take another shot at implementing something closer to the tabletop rules.
The tabletop rules also give tabaxi a bonus to climbing speed, but since that's not a thing in BG3, I've left in the falling damage resistance to compensate.
Note that the fur patterns have to be changed by selecting subraces, since I wasn't able to find a good way to switch out body textures in the appearance editor. If you've already created a tabaxi character, you won't be able to switch subraces, but using the attached "Retexture" zip, you should be able to retexture the default subrace to match one of the two new ones. The included readme.txt outlines how to set that up.
The new version of the mod is in the file Tabaxi02.zip. See: https://bg3.wiki/wiki/Modding:Installing_mods for an installation guide, and note that this also requires the mod at https://www.nexusmods.com/baldursgate3/mods/141
