Cats should not drink coffee. Coffee contains caffeine, a substance that is very dangerous for cats. Caffeine can cause significant problems for a cat's cardiovascular system, leading to large fluctuations in heart rate and cardiac output. Excessive intake of caffeine can also directly affect a cat's central nervous system, potentially causing cardiac dysfunction and even becoming a fatal factor.
In addition, caffeine can damage a cat's liver, heart, kidneys, lungs, and central nervous system. Therefore, cats should never be given coffee, and if a cat accidentally ingests caffeine, a veterinarian should be contacted immediately for treatment.
