Kaiju’s specific condition is gastrointestinal T-cell lymphoma. As cancers go, it’s a fairly common one in cats, but it is also—according to the kindly veterinary oncologist—one of the better kinds for them to get. The idea is not to cure it but to manage it, which is where the terrifying chemo drugs come in. But even the terror is not as bad as it could be, because it’s mostly about handling biohazardous material correctly—it comes in a bag with that scary symbol on it—and not so much about the effect that biohazardous material will have on Kaiju. Cats evidently deal with chemotherapy much better than humans do. And it presumably tastes better because it involves the irresistible salmon-flavored pill pockets.
