Given the task definition, example input & output, solve the new input case.
In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good.
Example: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Output: 5
The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.

New input case for you: This cat food was recommended by my vet because my 13 year old Cleo Cat was having trouble keeping any food down and was loosing weight. It stopped her problems. She doesn't eat as much as before since she seems to be more satisfied after eating which helps justify the added price. It aids in digestion since the...ok sorry...smells are gone if ya know what I mean. Had to add that so anyone experiencing problems with their cats can see there are a lot of benifits from this cat food.
Output:
5
