Pet rent

🪐 E.T 🪐

So I recently watched a Jenna Marbles video (she's a youtuber) and she spoke about that because she rents her house, she has to pay an extra fee every month, per dog. As far as I know this isn't a thing in the UK, I think it's ridiculous to have to pay extra just because you own animals. What do you guys think? Is this fair and do you think it should stay this way or not?
