Honey Bee Was a Critically Ill Kitten. Kate Was an Adult Cat With the Right Blood Type.

Honey Bee was eight weeks old when she came in to the rescue. She weighed slightly under a pound. Her gums were the color of skim milk.

The vet’s notes from the first hour read: severe anemia. Suspected immune-mediated hemolysis. Hematocrit catastrophically low. The kitten was not crashing yet. The kitten was going to crash.

The veterinary team did the things that veterinary teams do in those first hours. They started IV fluids. They started corticosteroids. They watched the numbers, and the numbers continued to fall.

At a certain point — and every vet who has worked with very small, very sick kittens knows the moment — the team understood that medication was not going to be enough. Honey Bee needed blood. Specifically: she needed feline blood. From another cat. Of compatible type.

Most people do not know that cats have blood types. There are essentially three: Type A, Type B, and the rare AB. Most domestic shorthairs in the United States are Type A. Some breed lines — British Shorthairs, Devon Rexes, certain bloodlines of Maine Coon — run heavily Type B. If you give a Type-B cat Type-A blood, the consequences are usually fatal within minutes.

Honey Bee was Type A.

The rescue had four adult cats in its small in-house colony of feline blood donors. Two were Type B, kept for the Type-B kittens. One was a Type A who had given blood three weeks earlier and was off-rotation while her own iron stores recovered.

That left Kate.

Kate was a five-year-old tortoiseshell who had come to the rescue herself two years earlier, as a young adult stray with a leg injury, and had stayed. She was not adoptable, the staff had decided, because she was nervous in the world but completely at ease in the back office, asleep on the receptionist’s chair, available for any cat who needed her.

She had given blood eleven times. The eleventh time, she had been pulled from a folded blanket on the office radiator at three in the morning. She had not seemed surprised. She had walked, on her unwounded legs, to the procedure room, and she had sat on the table the way cats sit who have decided that what is happening to them is acceptable.

The vet shaved a small square on Kate’s neck. They drew sixty milliliters.

Kate licked the inside of the vet tech’s wrist while it was happening, the way some cats do, the same way she had done it the previous ten times.

Honey Bee got the transfusion at one minute after midnight. By two, her gums had pinked. By six in the morning, her hematocrit had stabilized. By Sunday afternoon, she had eaten two-thirds of a wet-food saucer on her own.

The photograph the rescue posted on Tuesday was of the two of them. Honey Bee was lying on a folded fleece blanket, her small body curled into a comma, her ribs no longer visible. Kate had walked across the photograph during the photo session and sat down beside her — about six inches away, just close enough to be in the frame, not so close as to bother the smaller cat.

The caption read: This is Kate. She is the reason Honey Bee gets to be eight weeks and one day old. Kate has now donated blood eleven times. She is, by every measure, more useful than most people we know.

The post has been shared, as of this morning, eighteen thousand times.

Most of the comments are about Kate.

The other thing in the comments, repeated by a lot of people who had never thought about it before, is the question: Can I have my cat tested? Can my cat be on a list?

The answer, in most parts of the country, is yes. Most veterinary teaching hospitals — and many large urban clinics — maintain feline blood donor programs. The qualifications are not very different from a quiet adult cat sitting calmly on a table for fifteen minutes, two or three times a year.

Kate did not know about any of that. Kate licked the inside of a vet tech’s wrist, drank two saucers of warm Fancy Feast, and went back to sleep on the radiator.

Honey Bee is in a foster home now. She is gaining weight on schedule. She is going to be, in a month, the cat that some family that does not yet know about her is going to come pick up on a Saturday.

Kate, in the back office, is on rotation again. There are always more Honey Bees.
