Why: Macadamia nuts cause weakness, tremors, vomiting and a raised body temperature in dogs, and they are listed as toxic to pets by poison control. Keep them away from cats too — there is no reason to test whether cats tolerate them, and no safe serving.

If your cat ate macadamia nuts: Call your veterinarian or ASPCA Animal Poison Control at (888) 426-4435. Note how many were eaten. Weakness, tremors, vomiting or wobbliness need veterinary care.
