Real Estate / An increase of 25% rent is legal in Poland? [5]

Dear people,

I need an urgent help regarding my rent.

I have rent a flat in krakow for the last three years and there was no change on rent since I moved in. Current tenancy agreement will expire at the end of June.

Last night, my landlord sent me an email with new tenancy agreement with an increase of 25% in rent and a few % increase of czynszy, in total 29% increase. Generally, 3-5% annual increase can be acceptable, but I was not prepared for this at all.

Are there any laws to protect tenants in Poland? Is one month notice right? Could I be against this with a lawful support behind my back?

Thank you in advance for your help.

Travel / Transfer pets from Poland to Switzerland [2]

Hello,

I am moving to Switzerland (Zurich) in this summer with my two cats. Having looked through the Internet, however, reading all Polish seems to be never ending for me. Have anyone experienced to transport animals in cabin from Poland? LOT and Air Swiss can allow pets in cabin. My cats have EU passports and all vaccinations are already done. One thing that I do not know is about EU Health certificates and where and how I can get them.

Thank you,
