I have a cat who is a rescue. In the beginning she had diarrhea and that was attributable to her environment she came from, not her normal condition.Antibiotics took care of it. About a year later, she has a condition similiar to mega colon. About every 2-3 months, her poop backs up and has to be removed. I also give her meds now. Long story short, pet plan keeps insisting this is pre-existing and won't pay a penny, and eventually she might need colon surgery which would help this, and i know they probably won't pay on that either. I have argued with them to no avail. They are stubborn and wouldn't even send this up to a manager.I gave them a rating of 4 only because my other cat they were okay with on her last bill.
