My cat ate milk chocolate. Is he okay after 12 hours of symptoms?

Pet's info: Cat | Domestic Mediumhair | Male | neutered | 2 years and 3 months old | 10 lbs

My 10 pound, 2 year old cat ingested some Valentine's milk chocolate last night about 10pm. According to the label and weight on the box it seems the most he ingested was 34g/1.2oz. He did not vomit immediately, but did once during the night and had a little diarrhea. He is eating and acting normally. It has been almost 12 hours since ingestion. We have looked at the chocolate toxicity calculator, but thought we would ask here as well. Do you think he is in the clear now? Thank you!

Hello and welcome to Petco Pet Education Center, formerly Petcoach. With chocolate, often they will vomit out some of the chocolate decreasing the amount they absorb into the body. Also, clinical signs usually present within 6-12 hours of ingestion. If Jett is clinically normal now, just monitor. Any signs of hyperactivity, tremors, seizures, or continued vomiting and diarrhea, then bring him to a vet. Best of luck with Jett!
