Our bone broth is crafted from grass-fed beef bones which are gently simmered in small batches to create a delicious topper for cats. We have incorporated into our bone broth a unique proprietary species-specific probiotic blend which is cultured from wild mountain lions & domestic cats. This unique probiotic blend has been specifically selected to target and enhance the health of your feline's microbiome. Studies have shown that species-specific probiotics can optimize the balance of beneficial bacteria in your feline's gut, leading to improved digestion and overall gut health.
