So, that’s what makes all of his complaints even crazier! I’ve heard multiple stories about cats that wouldn’t even use a box after it’s been used once, or at least very high standards for cleanliness!
For mine, I have multiple different boxes for them, but they each have their own preferences. I have tried waiting until the box that my oldest prefers is so gross that he’s no longer using it, a d has moved to a different box, but even then, he gets crazy mad at me for touching it. I’ve tried sprinkling some used litter in the new box for him, so that it still smells like him, and he still gets very angry!
Can you direct me to any sort of source on that? I did a brief search, and I see some information about toxins found in tomato plants in general, (mostly stems, leaves, and green/unripe tomatoes), but nothing that specifically discusses a higher concentration in the “belly button” (I assume you mean the core/where the stem connects?) vs. the rest of the fruit.
