Foods Toxic to Cats
Cats metabolize substances differently than humans or even dogs. Many common pantry items are lethal to felines.
WARNING: Alliums (Onions, Garlic, Chives)
Onions, garlic, chives, and leeks are extremely toxic to cats in all forms (raw, cooked, powdered). They damage a cat's red blood cells, causing a potentially fatal anemia. Baby food or broth often contains onion or garlic powder—always read the label carefully before offering it to a sick cat.
Other Toxic Human Foods
- Grapes and Raisins - Can cause sudden, severe kidney failure in cats (and dogs).
- Chocolate - Contains theobromine, which causes abnormal heart rhythms, tremors, seizures, and death. Dark chocolate and baking chocolate are the most dangerous.
- Xylitol (Artificial Sweetener) - Found in gum, candy, peanut butter, and baked goods. Causes a rapid drop in blood sugar (hypoglycemia) and acute liver failure.
- Alcohol - Just a teaspoon or two of hard liquor can cause a coma in an adult cat.
- Raw Dough (Yeast) - Expands in the stomach causing severe pain and bloat. The yeast also ferments, producing alcohol, which leads to alcohol poisoning.
- Caffeine - Found in coffee, tea, energy drinks, and pills. Can cause restlessness, rapid breathing, heart palpitations, and muscle tremors.
- Macadamia Nuts - Causes weakness (especially in hind legs), depression, tremors, and hyperthermia.
- Xylitol (Artificial Sweetener) - Highly toxic, leading to sudden insulin release, causing severe hypoglycemia and potential liver failure.
In our experience
In our experience, a common mistake owners make when their cat stops eating is offering "human" baby food or meat cooked in broth to tempt them. You must verify these foods are 100% free of onion and garlic powder, which are frequent ingredients in broths and purees.
