Flowers are lovely and chocolates and candy taste so good! Be sure to have your cat avoid popular Easter Lillies as they can cause renal failure in cats. Also, you will want to avoid having your cat eat any chocolate bunnies or other Easter candy this year so that you and your cat can enjoy the day without a trip to the vet.
If kitty does get into something he should not have, please contact your vet immediately as time is of the essence. You can also contact the Animal Control Poison Center at 1-888-426-4435. Charges may apply, but it is well worth it for the safety and health of your cat.
