My cat was sick and not eating well so I bought this on advice of a coworker after my cat had gotten a force feeding and meds from the Vet. She wouldn't touch it! I was surprised because both my cats like to lick the milk out of my cereal bowl when I am done. I asked my Vet what the major difference was between cat milk and people milk, she said they are basically the same but cats milk has taurine added to it, a nutrient that cats need more of. The vet recommended to give the cat regular milk and a taurine supplement if she would eat that. Luckily, after second force feeding she started eating again so I didn't need to go that route. My Vet said that cat milk is way over priced for what you get. This can is also very large and you have to use it very quickly.
