Wish I knew about this sooner
I took in a stray cat who has issues with his teeth that was only noticeable whenever he ate so I only bought him soft food to eat. His breath was also quite rancid (only discovered when he cleans himself or licks me as a sign of gratitude). The vet recommended this product and he can eat biscuits without any discomfort and his breath doesn't smell like death. He has been so much happier since having this and actually enjoys it - I place it next to his food and he always eats if first.
