Smeagol has a weird anal gland quirk wherein she starts cranking gland stink whenever she becomes ecstatic (making biscuits, etc.). it was one of the first thing i asked the vet about when we adopted her but apparently it's not a health problem, just a thing some cats do. putting an Ecstatic Gland Stink feature on a cat who is regularly ecstatic and otherwise incredibly cute and sweet and loving is some top-shelf Mephistopheles bullshit.
