Every $5 from your order helps give a cat a home.

At PetCalm Co, we believe calm should be something every cat can feel — not just the ones who already have a home. That’s why $5 from every order goes directly toward supporting local rescue and rehoming organizations.
Your purchase does more than bring peace to your home — it helps another cat find safety, care, and love. From emergency shelter and food, to veterinary treatment and adoption support, your contribution helps turn fear into comfort for cats who need it most.

I absolutely love this. Being a senior citizen myself I was always worried about my cats health (over my own health) but these drops have helped my cats a lot. MooMoo loves the fishy flavor of this Hemp Oil and she can't wait to have it mixed with her food!

I recommend PetCalm Co. Hemp Oil to every cat owner whose pet is on commercial food. The precision dosing dropper takes the guesswork out, and the quality gives me confidence that I'm not sending clients home with contaminated or degraded product

I started using Hemp oil on my mother and daughter cat. The difference is noticeable and the mother finally has energy to play with her daughter as well as groom her!. Hemp oil has helped me with many issues with my 7 year old mother cat ranging from cardiac to gut issues.

Huge Difference!
First supplement that didn't stop working after 5 days. I've tried four other brands and they all failed. This one keeps going.

Tried 4 brands before this. Only one that actually helps with my cats range of health issues without my cat going back to old behaviors. Finally got consistent results
