I suppose there’s subtext implying her husband is an animal…
At least it’s not about taking an animal for a husband.
I remember Tom Lehrer (yes, I’m that old) quipping about a college student who majored in animal husbandry until they caught him at it one day.
Farmer hubby’s gonna soon be a former hubby!
So she’s calling him an animal?
