I live in an apartment in 55 + community in Oregon . I have a cat and left a $ 300 pet deposit when I moved in last June . I have been notified that my new lease in June will include a $ 30 PER MONTH charge for my cat . Is that legal ? I will be paying $ 360 a year to have a veil cat . I understand the deposit because the landlord wants to be protected against damage . But how can they justify $ 30 per month for allowing the cat to live with me ?
