It's easy to use and very palatable to even finicky eaters. I usually rub it on the gums to peak the interest. Give alone, or drizzle on peanut butter, and they feel like they are getting a treat. Compare this to Nutri-Cal or Nutra-Stat. The price is much more reasonable and the product is first rate. I'm glad this was available and highly recommend Revival Animal. I have ordered from them many times. Their product selection is great, as is their customer service. This product is a winner and I always try to keep some on hand. You never know when it will come in handy. Review: Worth every penny! - My old girl (cat) is having trouble keeping weight on and keeping food down. This product is AMAZING. She’s super picky, but gobbles spoonfuls of this down. I’m already seeing positive weight changes on her and she’s able to hold her other food down better. I’m a total believer in this product. ## Features - Doc Roy's FORTI CAL gel will help get your puppies and kittens off to a great, healthy start! - ENERGY - Doc Roy's FORTI CAL is the premier high calorie and energy supplement used to support healthy weight gain in dogs and cats. - SUPPLEMENT - Doc Roy's FORTI CAL supplies extra calories for weak or sick animals when they need it most. - SUPPORT - Doc Roy's FORTI CAL gives extra energy to performance, hunting, and working animals including cats and dogs. - GEL- Doc Roy's FORTI CAL is a tasty roast beef and liver flavored gel that your animals will lick right up! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DQB8C4G | | ASIN | B00DQB8C4G | | Best Sellers Rank | #198,682 in Pet Supplies ( See Top 100 in Pet Supplies ) #1,078 in Dog Multivitamins | | Brand Name | Revival Animal Health | | Customer Reviews | 4.4 4.4 out of 5 stars (429) | | Date First Available | June 30, 2013 | | Dog Breed Size | Small | | Flavor | Beef, Liver | | Is Discontinued By Manufacturer | No | | Item Form | Gel | | Item Weight | 4.25 Ounces | | Item model number | Rev-8458 | | Manufacturer | Revival Animal Health | | Manufacturer | Revival Animal Health | | Manufacturer Part Number | Rev-8458 | | Model Number | Rev-8458 | | Number of Items | 3 | | Package Dimensions | 7.36 x 3.58 x 3.15 inches; 4.25 ounces | | Product Benefits | Weight Gain | | Target Species | Cat, Dog | | Unit Count | 4.25 Ounce | ## Product Details - **Brand:** Revival Animal Health - **Flavor:** Beef, Liver - **Item Form:** Gel - **Item Weight:** 4.25 Ounces - **Product Benefits:** Weight Gain ## Images ![Revival Animal Health Doc Roy's Forti Cal- High Calorie Nutritional Energy Supplement - for Dogs, Cats, Puppies & Kittens- 4.25 oz Roast Beef & Liver Flavored Gel (3 pk) - Image 1](https://m.media-amazon.com/images/I/61H7qry3yAL.jpg) ![Revival Animal Health Doc Roy's Forti Cal- High Calorie Nutritional Energy Supplement - for Dogs, Cats, Puppies & Kittens- 4.25 oz Roast Beef & Liver Flavored Gel (3 pk) - Image 2](https://m.media-amazon.com/images/I/71DYGn8lC6L.jpg) ![Revival Animal Health Doc Roy's Forti Cal- High Calorie Nutritional Energy Supplement - for Dogs, Cats, Puppies & Kittens- 4.25 oz Roast Beef & Liver Flavored Gel (3 pk) - Image 3](https://m.media-amazon.com/images/I/51zLPsfWE-L.jpg) ![Revival Animal Health Doc Roy's Forti Cal- High Calorie Nutritional Energy Supplement - for Dogs, Cats, Puppies & Kittens- 4.25 oz Roast Beef & Liver Flavored Gel (3 pk) - Image 4](https://m.media-amazon.com/images/I/61GYPaXcKAL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Do you ship by usps?** A: Most of Amazon's products come via UPS or Prime Delivery, but some do come via USPS too.
