My kitten threw up string but seems fine. Does he need to see a vet?

Once he threw up the balloon and the entire length of string, he should be fine. The offending foreign body has left his gastrointestinal system. However you should really check your house for any more items like that including string, as a linear foreign body (string causing an intestinal blockage) is a serious problem and would need surgery to remove. So since your kitty regurgitated the entire string and balloon he should be okay.

Yes, this would not be uncommon but I would continue to monitor for any additional vomiting and for normal bowel motions for the next few days as a precaution in case not all was vomited up. Objects can stay in the stomach for months and do not always cause clinical signs (these are mostly related to actual obstruction of the GI tract so many small objects do not cause significant pain or vomiting if food can move around them)

I would definitely keep an eye on him, and if he vomits again or doesn't want to eat still, schedule a vet appointment. Issues such as minor GI upset, underlying illness, hairballs or obstructions, parasites, etc can all be possible causes of vomiting, which is why it's important to have it checked out if it continues more than once. If Lando seems in any obvious distress or pain (vocalizing, pacing, attempting to go potty but can't, tender to touch, etc), then he should be seen sooner.

Hi Sam! I can understand being worried about G. If he is the same as usual, I wouldn't be too worried. I would suspect you may have missed it. Continue to monitor him, and if he does start to appear to be sick, have him seen by a vet. Best of luck.

I would be concerned that Izzy could still have part of the string in her intestines or as the string was passing through her intestines it could have caused holes to form and now she has peritonitis. Izzy needs to get checked out by a veterinarian to make sure that she doesn't have peritonitis. If so she may require surgery to get better.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Tatum! The vomiting could be from residual irritation from the ribbon or there could be more ribbon that is causing an obstruction. It is also possible it is completely unrelated to the ribbon in general: intestinal parasites, hair ball, ate something else gross (plant, etc), pancreatitis, food allergy/intolerance, reaction to a new food/treat/table food. You can continue to watch him but if he continues to vomit or stops eating that is an emergency and he needs to see a vet for an exam and an X-ray to check for a blockage. I wish you the best!

If it was an isolated incident and she's not acting sick otherwise, I would just monitor her closely. If she does continue vomiting or develops diarrhea, lethargy or poor appetite, I would be concerned and would take her to your family veterinarian for an examination.
