Boosts energy
“This product literally saved my kitties life. We had been to 4 vets and none of them could explain or cure her ongoing diarrhea. They did multiple tests, changed her food, put her on medications, but nothing worked. After using this product for 2 weeks she was a normal kitty. She is no longer a " splat cat" and she has been able to gain weight, eat normal food, and have a great life😊”

Product Details
Ready Cal is an easy to use high calorie nutritional supplement that helps to provide the essential calories your cat needs daily to gain or maintain a healthy weight.
When our cats do not feel up to eating, it can cause low energy, depressed mood, and weight loss, which can quickly lead to malnutrition and further health issues.
This supplement helps to provide essential calories for cats that are not eating enough to maintain a healthy weight. Ideal for cats in their 'golden years' where maintaining weight is critical for slowing down the aging process.
Made in the USA with ten vitamins, seven minerals, and essential fatty acids, our vet formulated gel is designed for cats and kittens of all ages who may not be eating normally due to reasons such as stress, age, medical procedures, or illness.
Comes in a dial-a-dose tube for accurate dosing, with a natural fish taste cats love. Manufactured without artificial flavors or dyes.

Directions
To acquaint your cat with the flavor, place a small amount of gel on its nose or in the mouth.

Have you noticed lately a dip in your cat’s energy levels, a subtle change that has you wondering about her nutritional needs, or wondering if her age is catching up to her? As you embark on a quest to understand the world of high-calorie supplements for cats, rest assured, you're not alone in this journey. In this blog post, we'll unravel the mysteries surrounding feline nutrition, exploring the reasons why high-calorie supplements are essential, diving into the science behind things, and presenting statistical evidence that showcases their benefits.
Your kitty is a unique individual, and her dietary needs are just as distinctive. According to the American Association of Veterinary Nutrition (AAVN), many cats experience fluctuations in weight, either due to age, illness, or increased energy expenditure. In fact, studies indicate that up to 60% of cats aged 10 and older suffer from unintentional weight loss.
High-calorie supplements play a crucial role in addressing these nutritional gaps, providing your cat with the extra boost they need to maintain optimal weight and energy levels. A recent comprehensive survey by the American Veterinary Medical Association (AVMA) emphasized the importance of tailored nutritional plans, showcasing that a significant percentage of cats may benefit from targeted supplementation.
Statistical Insights: The Felines, much like us humans, can sometimes face nutritional challenges. The International Journal of Applied Research in Veterinary Medicine reports that malnutrition is a concern among domestic cats, with factors such as age, restricted diets, and medical conditions contributing to inadequate calorie intake. Conversely, feline obesity rates have seen an upward trend, affecting approximately 30% of cats in the United States.
High-calorie supplements emerge as a versatile solution to address both ends of the spectrum. They are formulated to offer a concentrated source of essential nutrients, aiding in weight gain for undernourished cats while supporting a controlled calorie intake for those on a weight management plan.
For cats in their golden years, often times, the first sign of struggle will be weight loss due to a loss in appetite. As the cat continues to lose weight, energy soon drops typically leading to the unfortunate end of the life-cycle. This is why ensuring that a cat maintains her weight and energy by using a high-calorie supplement can often provide a new lease on life.
Dr. Maria Rodriguez, a prominent feline nutritionist, sheds light on the science behind high-calorie supplements. These formulations are carefully crafted to be palatable and easily digestible, ensuring that your cat not only receives the necessary calories but also enjoys their meal. Research published in the Journal of Feline Medicine and Surgery supports the efficacy of high-calorie supplements in addressing nutritional deficiencies and promoting weight gain in feline patients. A quality, high-calorie supplement should consist of healthy ingredients to provide the extra calories. Ingredients such as salmon oil have the added advantage of supporting cardiovascular health as well as a healthy skin and coat.
Tailoring Supplements to Your Cat's Needs: A Personalized Approach Just as each cat is unique, so are their nutritional requirements. Consulting with your veterinarian is paramount to determine the most suitable high-calorie supplement for your furry friend. A study published in the Journal of Veterinary Internal Medicine underscores the importance of personalized nutrition plans for cats, reinforcing the idea that individualized care leads to better outcomes.
As your cat ages, her nutritional needs also change. At some stage, a high-calorie supplement will certainly become not just a solution but a companion in your cat's journey towards optimal health. So, as you provide for your cat, remember that high-calorie supplements are not just about meeting a caloric quota, they're also the key to possibly unlocking a new lease on life with boundless energy and health for your beloved whiskered companion.

muddypawsrescuenyc When he first arrived, he was in a bit of rough shape. He was found as a stray, so no one knows exactly what his past was like. All we know is that his future is as bright as his smile! After a few bags of @undertheweatherpet Chicken and Rice (which he gobbled up too fast for us to catch a good photo, yum!), and continuing medication for his stiff joints, Tavo is perking up and has blossomed into the most perfect gentleman.

Amazing results fast! Our Pitty was having a flare up and I decided to try this. He is now holding his leg up sturdy to pee again and has more energy it seems. I can definitely tell this product works! Definitely worth the money! Thank you!
olivemygolden The greatest product ever invented (especially if you have a golden that will eat anything ). I always keep some on hand & they always get used up @undertheweatherpet
Dawn P.
We love it!
Finally found a powder for my picky eaters! My cats don't like seafood flavored anything. It was a great relief to find this product. They happily eat it mixed with their wet food.
Instagram User Thank you @undertheweatherpet for all the wonderful products! Being a foster/rescue mom 🐾 and having rescued an anxious and picky husky 🐶, I can really appreciate your products!
We have freeze dried bland diet for dogs (a quick food replacement when I’m in a pinch - and SUPER healthy for your dog), hemp calming treats for prone to stress pups, and (I know we don’t want to talk about it, but so needed!) anti-diarrhea to help firm up those loose poops 💩!
Skye definitely is an Under the Weather Pup!

No longer ‘Under the Weather!’ Our 15 year cocker, Peanut, has multiple issues and most foods make her so sick and unhappy. But now she is dancing for dinner again. Also, she gets happy when she sees the kettle boiling as she knows what’s coming! Thank you for making such a good product for fur babies.

Review topics: [].
"The texture is messing with them. They want to eat it, but don’t want a big glob of it in their mouth. I mix it with another paste that they love eating but don’t provide what this paste does. I either do that or put it on the inside of a front leg so they’ll have no choice but to eat it."
"Been giving this to my baby for years now, off and on. Just to give her some extra suppliments and weight gain. She loves it."
"The product itself when I can get my cat to consume it is working well, he has at least maintained his weight and not lost anymore, he seems to smell a fishy smell and he HATES ANYTHING SEAFOOD so I would love if you had a chicken or turkey flavored weight gain, I only put it in one meal right now because he turns his nose up, I heat his fish under water add product then heat a spoon make a wet pile? And add his wet food and mix it in this is the best way after trial & error, I definitely will be getting another one , it's just he needs to eat so if he turns his nose up at his food I can't do it at every meal, but it's working and definitely worth it! If your cat eats fishy things they will love it!"
"Really helps,thanks"
"Give customers a chance to use the product and see results before sending surveys. Too soon to know!"
"My 21 year old cat loves this stuff! She is rather finicky with her food in her golden years. This gel gives her the extra vitamins and calories she needs to keep her feeling better."
"Cat would not eat it."
"My kittens don't like it. They are not eating it even if I mix it with other food. 😔"
"My cat absolutely refuses to eat this."
"It two doses for my cat to get used to it, now she loves it!"
