Cat was bleeding heavily out the anus. Four hundred and twenty dollars and four hours later, we're told that he has diarrhea. Reminds me of the time I went to the doctor complaining about lack of sleep, and was told I had insomnia.
The medical profession at large is such a swindle that unless something absolutely Earth-cracking is happening, it's best to just diagnose and treat problems at home. I had thought "bleeding profusely out the ass" was one such moment where they would actually be helpful.
