Blood in bile throw up?

So our cat, Catfish, broke his ankle three weeks ago.  He's been splinted since then.  The dr was able to set without any surgery.  His splint is up to his hip.  We have kept him in a room  with food and water and a litter box.  Eating, drinking and elimination has been normal.  He had a splint change (again no surgery) about one week ago.  He has seemed less active and somewhat depressed since then but we thought that was normal, given that he was a very active one year old before this.

The injury was getting caught in a grill type shelf, so there was no fall from a great height or anything, and anyway he's been totally normal for the last three weeks.  Never has been one to throw up at all.

Last night he threw up his food.  All of it.  And then I found bile throw up by his litter box.  And now he just threw up bile pink tinged, obviously blood.

What could POSSIBLY be going on here?  He's going to the vet but I am beyon distraught.  He has already cost us ~ $1000.  Could the splinting somehow be causing internal bleeding?????  What is going ON?

Feeling very desperate.  We cannot afford much more.

I can't see how the splinting could cause internal bleeding.  I really hope it isn't anything serious and the vet is able to take care of the problem quickly and easily.  However, if finances start to become an issue, there are a few options for you.

I really hope your little guy is okay.  He's been through a lot recently, poor little fellow.  Please let us know how it goes at the vet.

Sometimes the problem is with the food.  If you feed canned food, there could be a bad can in the lot. It happens.  If you feed dry food, have you just opened a new bag?  Because each new bag is a different lot, and if there are problems with a dry food, that's when it shows up. You can google "problems with _________" (the name of the food) to see if others are having problems with the same food.  If so, you can point that out to your vet too.  Before there are recalls, there are lots of complaints about the same food at the same time.  There are always complaints about just about every food at some time or other -- what you want to watch for are clusters at the same time

If he doesn't continue to vomit bile, that will probably be the end of the problem.  If he does continue to vomit, don''t waste time, get him to the vet.  The blood streaks are often just small blood vessels breaking -- like when you get a nosebleed after blowing your nose too much or too hard when you have a cold.  Continued vomiting can make that a lot worse.  If it's food poisoning, the vets have several things they can use that actually stop the food poisoning immediately by killing off the offending bacteria in the gut.  Don't wait a long time if vomiting persists.  If yuo suspect the food, boil some chicken for him -- that's very bland and will help his tummy.
