The Volas Silicone Pet Licking Slow Feeder Pad is listed as ideal for treats and mealtime enrichment.
Spread food or treats into the surface, then let your pet lick. The page does not name peanut butter, yoghurt or a freeze step. Use food that is safe for your pet; ask a veterinarian if you need diet advice. Healthier-eating marketing is not treated as a proven result here.
