My cat ate calming treats. What if they ate too much L-tryptophan?

Updated On September 23rd, 2025

One of my cats tore into their calming treats bag. I am unsure about how many could have been ate. My cats are acting fine. I’ve done some research on the ingredients and everything assures me they will be okay, except I don’t understand one ingredient. L-tryptophan.

L-tryptophan is just an amino acid, a constituent of proteins. Excessive treats like these ones could cause vomiting and diarrhoea. If that is the case, as a first approach, I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitely recommend a veterinary check up if the signs persist more than 48hours or you notice lethargy or inappetence.
