    • My picky cat actually likes it

      My cat is extremely picky, so I was shocked that she eats her food with KittyGlow mixed in without hesitation. Her fur looks smoother and she’s scratching way less. Highly recommend!

    • Amazing results for my senior cat

      I started giving KittyGlow to my 14-year-old cat who had been dealing with dry skin and shedding. After just a couple of weeks, her coat looks softer and she seems more comfortable. I’m honestly impressed — this is staying in our daily routine.

    • In love with this product

      I bought this for my cat and she LOVES IT! I’ve noticed an improvement in her gut health, and her coat is getting sleek and shiny. I also love that it supports her joints! I’ll definitely be buying this again.

    • Cat Approved!

      My cats love the taste of this product! I have an older cat and a young one, and they both enjoy it. It’s very easy to give, and they take it willingly with no issues at all. I’ve been using it daily for about a month, and I can already see how much shinier my younger cat’s coat has become…

    • It works, but it takes time

      I’ve stayed consistent with it and started noticing results after a couple of weeks. I’m hoping to see even more improvement as I continue. I just mix it into their food, and they eat it with no hesitation.

    • Great product for the price

      I’d been looking for a good collagen supplement for my senior cat to support her joints, but everything I found was either extremely overpriced or only available in chewable tablets that barely contained any collagen. This one is great — and it even has the added benefit of Vitamin C! The only downside is that I wish they offered…

    • Surprised

      I’d seen the ads and was a bit skeptical. I have to say, my cat is 19, and I’ve noticed a real difference. I only wish I had started her on this sooner.

    • Great product

      We’ve only been using the collagen for about a week, but all three of our cats love it, and we’re excited to see all the benefits it will bring them.

    • I love this — it really works!

      I’ve been using this for a month on my 16-year-old cat, and it’s amazing! I can see a huge difference in her skin and coat. Now I want to try the other products too!

    • KittyGlow did it again

      I found this product on Instagram and decided to give it a try. I have two cats, ages 12 and 9. Both were dealing with allergies and a Malassezia fungus that caused a lot of stress and vet expenses. Then KittyGlow Collagen arrived — and with faith and patience, I can finally breathe again. KittyGlow truly worked! Thank you for helping my babies feel better.
