Note: the verdict is different for each species — read the full explanation below before offering macadamia nuts to your pet.
Why is this the verdict?
Macadamia nuts are toxic to dogs through a mechanism not yet fully identified by veterinary science, but widely documented by the ASPCA and VCA: even a few nuts can cause weakness, tremors, and an inability to walk (especially in the hind legs) within a few hours. The condition is usually serious but rarely fatal when treated — it's still an emergency, though.
In cats, macadamia toxicity isn't well documented, and there aren't widely reported cases like there are in dogs — but precisely because of this scientific uncertainty, veterinarians recommend avoiding macadamia nuts for cats too, as a precaution.
