Healthy Pet. Happy Home.

Our story


How we got our start
Under the Weather was inspired by Ruffy, our founder's Wheaten Terrier, after going through a bout of digestive upset. The vet recommended a "bland diet" until healthy digestion was restored. After the inconvenience of cooking, our founder became determined to develop a more convenient solution.
What makes our product unique
As pet parents, we want everything we provide to contribute to a long, healthy, and happy life for our pets. All of our products are vet formulated with the highest quality ingredients we can get our paws on. We make our products better for your pet, and easier for you.
Why we love what we do
In addition to our commitment to pet health, we are dedicated to helping save the lives of shelter dogs. A portion of every sale supports rescuing, transporting and spay/neutering shelter dogs. It is our passion to help animals find loving homes and stay healthy in mind, body, and soul.

Product Description

Ready Cal High Calorie Supplement

How many calories are there in a teaspoon of Ready Cal?

There are 28 calories per teaspoon.

Once opened does the Ready Cal need to go into the fridge?

No, it is still shelf stable as long as the cap is put back on! This product has a shelf life of 2 years from date of manufacture.

Where is this made?

Under the Weather is headquartered in Vermont, USA. Ready Cal is manufactured in the USA using ingredients from trusted sources around the country and world.

Can this be added to my pet's food?

Yes - We encourage you to serve in whatever way is most convenient for you and your pet.

What should I do if my pet doesn't like the flavor?

We recommend you try placing the Ready Cal on the top of your pet's paw or nose. Most pets will instinctively lick it off. If not, try mixing it with a bit of warm water and adding to their daily food. You might also try putting it on a treat!

For Kittens, Puppies, Dogs & Cats

Why a High Calorie Supplement?


Weight loss can quickly lead to malnutrition and further health issues. Adding a high-calorie supplement will help provide essential calories your pet needs daily to gain or maintain a healthy weight. This supplement can also help to stimulate your pet’s appetite and boost their energy.
