A sentence about cats

I read this great sentence the other day, about cats, but I can't find it. And I don't even know if I read it yesterday or if it was days ago, it can't be that hard to track down, I haven't read that much in the last few days. I've been reviewing sections of The Passion According to G.H., but I can be fairly confident that's not where the sentence is from, there are no cats in it, just the cockroach, and the drawing of the dog on the wall, it was a dog, wasn't it? So maybe the new book I started, Salki, fortunately I'm not very far along, I can just skim back to the beginning, but no cats, just that fabulous description of Krakow — they might've been Polish cats — and I already don't recognize so much of this book, how can I say I'm reading it if I can't even remember five pages ago?, but the tone, the listiness of it, feels a little like my cat sentence, maybe it comes from a part of the book I haven't read yet, so I check the review that spurred me to acquire this book, but the sentence isn't there either. The review notes a similarity to Perec, and I recall having looked at some of my notes on Life: A User's Manual, and though I don't recall any cats in the text — no, I don't think they were French cats — just that great picture of Perec with a cat on his shoulder — I check my notes again to be sure, but no cat sentence. The only other things I've read in recent days are a few articles, some reviews, nothing noteworthy, nothing I saved or bookmarked, how could I have let such a great sentence pass me by, unmarked, I fear it may be lost forever.

The sentence went something like this, about the change of season transpiring over their alley world, and how the outdoor cats were noting the changes and somehow plotting, and the indoor/outdoor cats feel unprepared, caught between two worlds, while the indoor cats watch the outdoor cats and can afford to feel smug but are also a little bit jealous, or wistful, all the cats in their alley, I can picture it, definitely they feel like Montreal cats.
