Well... believing that meditation and mindfulness are supposed to make you happy is a misconception. They are tools for helping you calm and examine yourself, so you can make happiness a possibility, because you are managing stress and anxiety and setting realistic, rational priorities on everything.
They are the broom that sweeps the path clean... the path still goes where it goes. Changing paths is a conscious effort... you have to do the work.
Cats aren't domesticated... they are wild animals who choose to cohabitate with people due to a symbiotic relationship. Grain storage drew mice, mice drew cats, humans realized cats were keeping mice out of their grain... didn't murder all the cats.
Your cat will cohabitate with you with no social interaction at all if that's how little effort you put into it. If you want a relationship with your cat, you have to spend time with it and learn to speak cat.
