I fed our cat some raw milk
Do you think that is appropriate?
In the wild there are more dangerous things they eat out there. A little milk is just a drop of water for them.
Grown cats should eat balanced cat food. Cow milk was not designed for consumption by cats.
Cats are pure predators and they don't need processed junk like kibble.
Your intentions to feed cats well are great, but cow's milk is still highly processed. Your cat would love it if it ate a balanced diet without milk, and it would be much happier.
