My sick cat vomited dead worms. Is she okay? What should I do?

Poor Frodo! Some cats do vomit during deworming due to the strength of the medication combined with the parasites moving through the GI system. These side effects should only last a few days, so if it's been longer than that, I would be concerned that it could be due to something else, such as a GI illness, a foreign body, or pancreatitis. I recommend withholding food for 12 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Tifa! Thanks for the pictures! The spaghetti noodle things in the vomit are adult round worms, which are an intestinal parasite. Since Tifa is lethargic, not eating and profusely vomiting I would recommend taking her in to the Vet. Hopefully with some supportive care and deworming medications we can get her back to normal. I have, in rare cases, seen intestinal parasites cause an intestinal obstruction. I hope this helps and I wish Tifa a speedy recovery!

Poor kitty! She could have a severe GI illness, may have eaten something rotten, a foreign body, or pancreatitis. I can give you a home remedy to see if that helps. I recommend withholding food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. I hope this helps!

It is rare for worms to kill a cat unless they cause a full obstruction of the bowel with severe, persistent vomiting or extreme weight loss. It would be important to deworm her within the next 48hours and to schedule an emergency vet assessment if she becomes weak

Yes, although it is gross, he should be fine until you can see your veterinarian. If you can, save the vomit for your vet to confirm roundworm infection. Do not offer any food to your cat tonight. A small bowl of water or unflavored PediaLyte can be left out.

Oh no it's not good that Kitty ate that vomit! At most, I would expect that eating this vomit could cause some GI upset, causing her to vomit and/or have diarrhea. It's good that it doesn't look like she has eaten the plastic bag, and if she ate the bag, I would be concerned that the bag could cause a foreign body obstruction. Keep an eye on her for now, and if you see any vomiting or diarrhea, I can give you a home remedy to see if that helps her. I recommend withholding food for 12-24 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, the diarrhea continues on the bland diet, she stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. Good luck, I hope this helps!

With so many complications i recommend you get a full health assessment by your vet in order to identify and prioritize her issues. Working unwell cats needs to be done carefully using mild products carefully calculated for their weight
