I am currently playing on a Fabric world, 1.19.2, and encounter something rather peculiar. Once I changed my cat over to the queen variant, the sitting and walking animations didn't seem to work anymore for the cat. Would you by chance have any recommendations or fixes?

Are you running any resource packs / mods alongside Queen Cats & Dogs?

This issue has been finally fixed in 1.0.3, which will be released alongside the forge version, thanks a ton for reporting it!
