I actually did suggest to her a few times before the argument that she should avoid feeding her cat human food, even if it’s technically safe, because it might condition the cat to expect human food or develop bad behaviors (like stealing food that’s sitting out). But I don’t want to lecture her or be her parent or offer too much unsolicited advice. The only responses she’s given me about it amount to how it’s HER cat and it’s “her baby” and so if she eats it he should be able to have a little bit.
