It’s empty in here!
These work and importantly smell nice, having tried another brand which really smelt bad I’m happy to feed these to my cat. She has no dental issues so this is more preventative. The heart design and colours are just a bonus
These are an interesting and different treat. They definitely have a minty smell. One of my cats loves them. However my other cat, who has both her top and bottom canine teeth on the left side of her jaw missing, struggles with them, This may be a cats preference as even if I break them into bits, she still can't really manage to eat them, so it may just be that the doesn't like the taste. My cat that eats them would eat anything put in-front of her that was edible!
