Here is important information from a previous post with an emergency:
Call the ASPCA Animal Poison Control Center
The telephone number is (888) 426-4435. There is a $55 consultation fee for this service.
Be ready with the following information:
– the species, breed, age, sex, weight and number of animals involved
– the animal’s symptoms
– information regarding the exposure, including the agent (if known), the amount of the agent involved and the time elapsed since the time of exposure.
Have the product container/packaging available for reference.
REMEMBER: Bunnies cannot vomit like a cat or dog to get the poison out so it is really, really important to consult a vet ASAP as they have treatments available. Most likely fluids will be administered, depending on what the properties are of the ingested product to flush their system.
Here is another # I do not know if they charge a fee:
National Animal Poison Control
Center 1-800-548-2423
I would still call the emergency vet today and see what they say, and possibly take your bunny in. How much was consumed? Let them know.
