Why is caffeine (coffee & tea) bad for cats?
Cats are obligate carnivores: they must get certain nutrients (taurine, arachidonic acid, preformed vitamin A) from animal tissue, so a complete, balanced cat food should always be the base of the diet. The food on this page is the exception that proves the rule: cats' small bodies and unique metabolism make certain human foods genuinely dangerous, not just "unhealthy." If your cat has eaten it, treat it as urgent.
Coffee, tea, energy drinks and their beans/grounds hold methylxanthines — the same toxins as chocolate — and are unsafe for cats in any amount.
"ASPCA groups chocolate, coffee and caffeine together: methylxanthine concentrations cause toxicity (stimulation, heart effects, seizures)." — PetMD

- Call immediately. Your vet or ASPCA Animal Poison Control (888) 426-4435 — cats hide illness, so do not wait for symptoms.
