What is it like to live worse than a cat?

I think about buying toys and snacks for them every day, and I am also afraid that the cat food I buy is not good and the snacks are not good for them. To sum up, they have nothing to do every day. I do it for her. The two of them are going to eat dirt. They eat well, play with them, and use them well. I really can't bear to let them go and wear them. Sometimes I think that I will be a cat in my next life, and I will be a responsible cat for others. Sometimes I feel very doubtful about life. It feels like they don’t have to think about anything. Someone is taking care of them every day to eat and drink. They are very happy.
