Diet Transition Guide: Avoid Digestive Upset with a Careful Diet Transition.

Rayne uses unprocessed, whole food ingredients, wherever and whenever possible. Whether you have been feeding store-bought, homemade, raw, freeze-dried, or other therapeutic diets from your veterinarian, your pet's system is going to need time to adjust to their new dish.

For many pets, transitioning diets over the course of ten days is sufficient, but some may need a little more patience and time. 

That's okay! 

Our step-by-step guide will help ensure you and your pet are set up for success.

A Little Patience Can Go a Long Way When It Comes to Helping Your Pet with Their Diet Transition.

Vet-Recommended Tips and Tricks

The typical transition to a new diet can take 5-10 days, but depending on your pet, their preferences, and their medical profile, that can vary.

Be sure to provide plenty of privacy. Although we want to watch and evaluate what our pets think of a new diet, our attention can be off-putting.

Cats are particularly discerning, so don't be frustrated if they take a little longer. Taste, texture, and temperature all play into what your cat chooses to eat. Cats have unique nutritional needs and should never go more than 24 hours without eating. If your cat is not eating, please connect with your veterinary team.


Help! Vomiting, Diarrhea, Gas, Constipation!

If your pet refuses to eat, develops vomiting, diarrhea, or excessive gas, or experiences constipation, it maybe that the transition is happening too quickly for them. Please contact your veterinary team to ensure there are no concerns, and then, if appropriate, try making the transition to the new food more gradually.
