Thank you for asking your question on "just answer."
I need a little more information about her please.
1. Is she still eating and drinking today? Is she keeping it down?
2. Have you changed her diet, or treats, recently?
3. Did the red fluid look like blood? How much was there?
4. Is she acting abnormally lethargic or depressed?
5. If you lift up her lip, what color are her gums?
1. She's eating and drinking some but not as much as usual. I've only seen a few pieces of cat food come up. It has been mostly phlem-like fluid. Which isn't that unusual for her. We have always dealt with a lot of sinus infections from the time we found her as a stray when she was 3 months old. It took almost a year to get her healthy but she gets reoccurring infections because of an abnormal growth/positioning of her sinus cavities. Usually if she gets congested for a week or so we treat with Clavamox for 10 days (2-4 times a year) and she has some grass to help settle her stomach. She had a heart attack 2 years ago and has been on aspirin therepy since - approx. 20 mg. 3x a week.
2. No diet or treat changes.
3. the red fluid looked like watery phlem with more than just a pink tinge...a red color.
I caught it on a napkin and a handful of white tissues and it was definitely red but quite watery and no clots. Total quantity was about 4 tablespoons.
4. I have been out-of-town taking care of my elderly mother for three weeks and need to return tomorrow. She has been depressed with me gone and crying for me. Today my 18 month old granddaughter is here so she has been staying out of sight.
5. Her gums are mostly black...always have been but when I can see color they are relatively healthy looking pink.
That was a great information.
Sometimes when they cats vomit repeatedly, or have strong gastrointestinal contractions during vomiting, small blood vessels in the esophagus can burst cause there to be a tinge of blood in the vomitus.
Since she is vomiting phlegm, it is important to make sure her breathing is normal. If she were having difficulty breathing, coughing, or her gums were very pale then she may have congestive heart failure. But that is the worst thing I can think of. It sounds like her breathing is normal, and her gums are pink, from what you describe. Just had to mention that because that would be cause for an emergency trip to the vet.
She could be vomiting from stress. Stress of you being gone and different people in the house.
I would pick up her food and water for the next 3 hours if she is vomiting.
Three hours after her last vomiting episode, you can offer her a few sips of water.
If that stays down for half an hour, you can gradually offer her more water.
Once she is keeping the water down, you can offer her a bite of plain chicken and white rice. This is a bland diet for her gastrointestinal tract. if she keeps the bite down, you can gradually offer her more.
You can give her 1/4 tablet of pepcid AC or zantac. These are over the counter stomach acid reducers that are safe to use in cats. You can purchase them at the drug store or grocery store. This should help settle her stomach. You may repeat the dose every 8 hours.
Do not give her any more grass right now. The grass is like sand paper on her stomach lining when it is inflamed or irritated.
As long as she is acting fairly normal and her gums are pink. It does not sound like an emergency right now. But she may need to see a vet if she can not keep food, or water, down for 24 hours as she will become dehydrated. If she continues to vomit repeatedly, or there is more than a few drops of blood in the vomitus, she needs to go to the vet right away. This could indicate internal bleeding and the need for further treatment.
I hope this helps.
Being the vet, I always have to list the worst possible things it COULD be. But it does not mean that it is not something simple like she had an upset stomach and eat grass which irritated her stomach lining.
The "coffee ground" vomitus is from bleeding in the upper g.i. tract. You are right. If you ever see anything like that in a cat, or dog, get them to the vet right away. It is not very common in pets and indicates a large amount of bleeding.
Start the Pepcid AC, or Zantac, now if it will not stress her out to the point she vomits again. If you think she will accept the medicating, then do it now.
And don't let her drink more water right now then. If she drinks too much she will vomit again.
The fastest way is to tilt her nose to the ceiling. This causes her mouth to open. Pop the pill in the back of her throat and hold her mouth closed. Putting a drop of water in her mouth, after the pill will cause her to swallow. Also wrapping her body in a big towel, like a burrito so only her head is sticking out, will help.
But, some cats are tough to medicate. If she is strong enough to tear you up and fight, then she can not be that sick.
You could put it in a small piece of chicken. It is only 1/4 of a tablet which is not very large.
You, and she, are very welcome.
I hope she feels better soon.
