Our cats just go wild for Pet Naturals of Vermont’s line of kitty chews. Although we started to help with the horrendous hairballs, they’ve evolved into a great treat for our cats and they can hear us opening a bag a mile away. A bonus: they are full of good things for feline health and make our kitties’ coats look amazing. We recommend their Calming for Cats formula for stressful vet trips (we’ve even tucked a small bag into our evacuation kit so we’re all set).
