## Product: Hill's Prescription Diet A/D
**Brand:** HILL'S

## Pros
- Successfully encouraged a picky puppy to start eating again
- Helped improve the health and vitality of the puppy within a few weeks
- Suitable for use under veterinary guidance before switching back to a regular diet
- Encourages picky cats to eat, especially with the high-fat content
- Offers a good balance of functionality and expected performance
- Provides solid value for its price
- Allows purchasing a full case instead of single cans for convenience
- Offers a cost-effective alternative to vet purchases
- Endorsed by veterinarians, adding a layer of trust and reliability
- Contributed to the health of a 16-year-old cat, indicating suitability for older pets

## Cons
- The cat initially enjoyed sample cans but refused to eat the regular, identical product upon arrival
- Difficult to review due to the finicky nature of some pets
- Size of the product is smaller than expected for the price
- Some cans arrived opened and leaked, causing a loss of over $9.00 worth of food
- Requires vet approval for purchase, which might be inconvenient for some pet owners
- The product's appeal may vary among pets, as evidenced by picky eating habits

## Bottom Line

This veterinarian-endorsed product has helped pets with eating issues and health concerns, especially in older animals. It offers good value and convenience but may face delivery and acceptance challenges with finicky pets. For very selective eaters, alternatives like Royal Canin Veterinary Diet might be more reliable.
