Hello. Thanks for writing in. My name is***** and I would be happy to help you. While you may see some symptoms of illness within 6-12 hours of ingestion, kidney failure can actually take 24-72 hours to develop. If you haven't seen any of those symptoms yet, chances are he did not eat any of the plant, but those symptoms may not show up 100% of the time before kidney failure develops. So, I wouldn't say that he is out of the woods yet, but I suspect that he hasn't been poisoned at this point. It only takes 2-3 leaves to cause toxicity. Even licking the pollen off themselves can be toxic. If he was my cat, I would monitor him for any symptoms of lethargy, anorexia or vomiting. If you haven't seen any of these symptoms in 3 days after ingestion, he will most likely be fine. If you do notice any of these symptoms, though, I wouldn't hesitate to get him immediate veterinary attention, even if it is the emergency vet. You want to treat before kidney failure sets in. If you wait until after that time, the prognosis for recover is very poor. The website below will have more information on this toxicity. Please let me know if you have any other questions or concerns. Hope this helps.
