Melatonin is, in general, not a toxic drug. however, little is known about toxicity in dogs/cats. Adverse effects reported in humans include altered sleep patterns, hypothermia, sedation, tachycardia, confusion, headache, and pruritus. the main concern would be the sedation, if it becomes too noticeable then it might be a good idea to take him to your vet in order to get him checked. if he ingested the pills less than 2 hours ago i would also recommend taking him to your vet to get an injection to induce vomiting.
