The Next Poster

Not really sure why I decided to put this in Gryffindor, but whatever.

Here are the rules.
I'll start by making a guess about the next poster. For example "I think the next poster is wearing something blue" or "I think the next poster can see a cat" or "I think the next poster is in America". The next poster then confirms or denies my guess and makes one of their own.

I'll start.
I think the next poster gas a pet cat.
