This companion piece to the "My cat was playing with a string, then ate it. Is this a problem?" FAQ. answers a reader who is aware of the dangers of string ingestion but is wondering when signs will show up if the string is still in the gastrointestinal tract.
"I have a 3.5-month-old kitten who decided to chew off and swallow the elastic string portion of his toy. He passed quite a bit of the string in his stool today, however, I do not know if more is present in his intestines. Does anyone know how soon after ingestion of string that a cat might show the signs and symptoms of a linear foreign body (string stuck in the intestine) such as lethargy, vomiting, and fever?"
Thank you for your question. You are correct to be concerned. How concerned will remain to be seen, as it is probably impossible to know how much string was ingested.
Possible clinical signs from string ingestion
- Vomiting or dry heaves
- Anorexia or decreased appetite
- Straining to defecate or diarrhea
- Painful abdomen
- Dehydration (due to vomiting)
How Soon Will Signs Be Seen?
The appearance of clinical signs can be immediate, or more long term, depending on the amount of foreign body material ingested and where it is hung up (if at all). I once saw a young cat who had eaten rubber tubing 2 months prior! The cat had not been 100%, but was still eating, active, etc. Typically, signs will appear 1-2 days.
The good news is that you did see string being passed without apparent trouble. If a string is seen either under the tongue or protruding from the anus, it is important to never pull the string that may be visible.
This can make the damage much worse as the string "accordions up" the gastrointestinal tract, possibly tearing fragile tissue.
I would still recommend seeing your vet for a quick check. This is definitely a case of "an ounce of prevention is worth a pound of cure." If there is any string present in the gastrointestinal tract, the longer you wait leaves more time for tissue damage, infection and possible rupture to occur.
Your vet can help you determine the best course of action.
Your vet will start with a physical examination and palpation and that may be all that is needed. If there is any question, additional workup may be performed; such as radiographs or blood work.
On a related note
Please use supervision and caution with pet toys. Toys are great for fun and exercise, and I do recommend them. It is important to anticipate that pets may break, tear, or as in this case, ingest part or all of a toy, causing problems.
