People often ask me what food triggered Harpo's IBD, so they can avoid it, & I'm like, "every cat is different, food sensitivities are really complex and can change over time." Like Harpo LOVED plant foods. He shared my vegetarian food for over a decade. But he grew sensitive to plant foods later.
Yup. When the topic comes up, I put it this way: it’s the same as being lactose intolerant for people. Some people start out like that as babies, but others (like me) don’t really run into lactose intolerance until they’re in their 30s, and it’s not like flipping a switch. It’s **gradual**.
(… And then I got pregnant in my late 30s and the lactose issues abated somewhat, but only until baby was done gestating. Practically the only thing I miss about pregnancy.)
I grew up drinking a large glass of milk at every meal. I didn’t drink nearly as much as an adult, but I still consumed a lot of dairy products. It’s only since menopause that it has started bothering me.
I never thought about that aspect of the timing. Mine started at about that time.
