Maybe it sounds like major redflag? It sounds a bit manipulative. People use it to lie and to get out of out of their obligations? Typical "feighning suprise" is with pet attack. "It does not bite". What a big suprise when it does bite, it "never did it before, did you provoke it"? Later you find that thing send 5 people to hospital, and entire street has delivery services suspended.
