Pet rent

I offered my landlord $100 a month to be allowed to have a cat. He said no because he would prefer that I move so he can raise the rent.

Land Lords are the dumbest leeches

You're so close to the answer, yet you can't bring yourself to do it, which is the whole problem:

Tell your freeloading cat to get a god-damned job. If your relationship can't withstand that level of honesty, you guys have deeper problems.

Simply don't tell them you have pets.

afaik in germany you can just get a cat even if you signed that you wont get any pets at all and they cannot do anything about it ... unless someone closeby has cat hair allergies etc
dogs are a different story
- I looked into it, and the law is fuzzy, because it states that you are allowed to have “small animals” but it never defines what a small animal is
Yeah at least in Canada, a landlord can't kick you out for having a pet so you just dont say anything :)
- If your tenant has a moose or a bear, then he's in charge now.

Give your landlord a bill for mice hunting services.

Oh I thought you meant sending pictures of your pet when they interrupt an online meeting. Is that called cat tax? Anyway, your cat may not have a job but it can pay in tasteful nudes.

He can pay in cuddles.

Oldest profession.
- Wait what? You can pay people to cuddle you?
  EDIT: Oh, nevermind, I just looked that up online.
- Technically they were mousing professionally long before they were emotionally prepared for cuddles with us.

So was I, and I still had to pay bills.

"Monetize that baby!"

We need UBI for pets

The things americans invent to make other peoples lifes hell is incredible

Why does it look so happy on this picture?

Because he unemployed.

This is typically for insurance. Some don't insure against pet damage, but even a well-qualified tenant's pet can cause damage that the tenant themselves would be unlikely to, and this can easily exceed the deposit. This type of liquid damage is typically not covered by rental property insurance and can be very stubborn (think, odor).

Your cat should claim unemployment benefits. Socialism. The answer is socialism.
