I've been posting a lot because I've never had an animal spayed and I'm worried. They said they gave Mixy a tattoo to ensure she's been spayed. And there is a small line which I've been guessing is the incision and a circle right above it and I was guessing that was the tattoo. But after looking at the incision is has a green line making me think it's the tattoo and incision? But if that's the case I have no clue what the circle is.
