I was speaking to a woman today in the waiting room of my psychiatrist's office. She was asking me about my service dog, and then she said her son was going to call his cat an emotional support animal because his landlord didn't allow pets. I said great, all he needs is a letter from his doctor stating he has a disabling mental illness and needs the cat as part of his treatment! The lady said oh. I said, it might be easier to just find a landlord that allows cats, than to convince a doctor that he has a serious mental illness. She said good point, she'd suggest that to him. Duh!
