One cat, aged 12 1/2. One human, aged 19 months. Cat barely tolerates human. Human adores cat and clearly doesn't understand she isn't well, is old, and doesn't want any attention. She has just hissed at him and lashed out. I have put the cat out and told the small human not to lay with her, but what can I do? I refuse to leave the cat in her room all day. It is her house too and it feels mean.
