She quit eating these things but for several years, one of my cats just loved olives, whether green or ripe, and she would drink the juice if I let her. She also loved pineapple.
Although it has been a couple of years since she has eaten these things, she still begs for olives whenever I have any out. It's as if she still has the memory of liking them but, once she is offered one, she quickly loses interest.
Perhaps that's not so strange, after all. Every now and then I will buy a package of Mallo Cups because I used to love Mallo Cups when I was a kid. Before I have completed even half of even one of the two cups that come in the package, I've had enough, as I now find them to be sickeningly sweet, and not something that I care for at all. Perhaps it's like that with her.
In the event that someone feels compelled to tell me that either olives or pineapple are not good for cats, you may be right, but she is twenty-four years old and, aside from some arthritis, she's doing pretty well.
