<human>: Condense the text into a few key points

So my family owns a cat, he is by far the best cat I've ever met in my life (and I'm not just saying that) but he has a cough, and he has ever since I've met him. I thought he had asthma or something but his cough has been progressively been getting worse, and I've asked my dad about it (the owner of the cat), trying to tell him of his problem. At first he told me that Diego (the cat's name) has been to the vet and is fine, but I just found out this has all been a farce when I called the vet and asked what it sounded like, they said it would take 20 $ for a checkup and 16$ for an xray and an uncertain amount after that for the fix-when I told my dad he finally said he would never spend any money on a cat, I don't know how he justifies this and I don't have the kind of money that could solve this problem. I'm just tired of seeing the animal suffering.
<bot>: Family cat has a cough, (father) owner is an asshole and doesn't care enough to fix the problem. I am a college student, I cannot afford to fix the problem.
