Shadow, you is still one of my bestest buddies, ya knows that, and ya know how the big Bump is.
It depends on knowing your cat, you in a general you, and what you are feeding your cat, and what has changed, in the food, in the sched, in the household routine, etc.
Came home from a show, to 2 sick 12 week old kittens, throwing up and diarea, OK, what had changed in 2 days. The pet sitter, at that time, said they gave them adult foodies in stead of kitten foodies by mistake. Thats what changed. They both went into the vet, x-rays showed they both had inflammed intestines, they were put on Metronidazole, all better.
Bump threw up, on a holiday no less, called my vet, she asked, what has changed, well um, they all had a little milky. She told me to just give him baby foodies mixed with water at next feeding, if still throwing up, in he comes, and oh no more milky. What had changed? the milky. He kept his baby foodies down, and ate normal at the next feeding.
Tried to save money, gave the kittens FF, they both threw up, what had changed? The FF, gave them BW next meal, they were fine.
Gave Prowler and Smokey FF, they threw up, OK, a pattern is forming, what had changed, the FF, they went back on BW, they were fine.
Smokey would not eat her breakfast, eating is her mission in life, she went to college for it, nothing had changed, I know how she is about eating, in her case, I called the vet that morn, in she went. Many tests, specialist called in, told to take her to the ER, she had liver issues, I know her, when she won't eat, there is a prob, I caught it early.
Just a few examples. I know my cats, I know when something has changed, and we all know Bump is on the overly pickey side, mol, ain't no one else out there, more than him.
If nothing had changed, and they were eating the same foodies, then there is something else going on. They should not miss more than one meal, if they won't eat by the 2nd meal, they should go in. You want to be very careful of dehydratration.
Now Bump gotta go to NYC, Dallas is playing there tonight, so you is on your own now, mol, Bump still got time to detour to Canada, and getty Shadow, ya got 2 hrs, for them to either eat, or take them in. By the way, got a place, near you, where Bump can land his little jet?
