I think with this kind of surgery it’s going to be expensive either way as it is exploratory so not routine - if they’re lucky it’s obvious and easily removed, if not they need time and skills to go around hunting for the ovarian remnant.

For now I think it’s just wait and see. He wants to figure out if he can try and recoup some costs from whoever spayed her, but at the same time sometimes these remnants occur due to unnatural growth, rather than from a botched spay…

If it’s just two to three weeks of the year, it could be managed by keeping her to one room with the easiest to clean surfaces and the bathroom, taking any electronics, bags, etc out or putting them in an inaccessible location. And checking for pee twice a day with a UV light, and wearing earplugs at night for the yowling… What was frustrating was that her most recent cycle happened in winter, that’s less predictable than if it happened in summer
