I've been giving my strictly indoors cat vitamin D3, and it did wonders. Should I continue?

Thanks for reaching out! It's great to hear that you're thinking about your cat's well-being. Vitamin D3 is essential for many bodily functions in cats, just like in humans, but giving your cat extra supplements might not always be necessary or safe, especially for an indoor cat. Cats typically obtain all the vitamin D they need from a balanced diet — if you're feeding a high-quality commercial cat food, it should already have the proper amounts included.



Supplementing with extra vitamin D3 without veterinary guidance can actually lead to vitamin D toxicity, which is serious and can cause symptoms like vomiting, weakness, increased thirst, and in severe cases, kidney failure. Monitor your cat for any changes in behavior, appetite, or bathroom habits, as these can be early signs of an issue.



For safe at-home care, ensure your cat has a nutritionally complete diet and plenty of enrichment to keep them happy and healthy indoors. If you've noticed your cat's health improving with the supplement, it's worth checking if dietary tweaks can naturally sustain these benefits.



To get a personalized recommendation and ensure your cat remains healthy, I suggest booking a video consult with Dial A Vet. That way, we can discuss your cat's specific needs and evaluate if continued supplementation is necessary.
