Pet's info: Cat | Feral | Male | neutered | 1 year and 11 months old | 9 lbs

My cat was nibbling on my daylily plants and might have eaten a small piece of a leaf (perhaps the size of a raisin or dime)! Is this plant super poisonous to cats? And how much is toxic? What should I do?! please help!!

Unfortunately the daylily is toxic to cats, and clinical signs usually occur between 6-12 hours after exposure. Watch out for lethargy, increased drinking, increased urination, racing heart beat, increased heart rate, vomiting, and diarrhea. If you see any of those signs, rush Dewey into a vet immediately.

    Thank you for submitting your question regarding Lucky. Unfortunately, lilies can be very toxic to cats even in small amounts. Furthermore, most parts of the plant are toxic including the pollen. I recommend that he sees a veterinarian even if he is acting normal. He should have bloodwork tested to assess his kidney function. I hope this information helps!
