I was drinking my coffee the other day and I accidentally spilled some on the floor (a couple of drops).

My cat licked them. I don't really think this is a big deal because it was only two drops, but can anything happen to cats if they drink a (relatively) large amount of coffee?

According to, caffeine poisoning is "[g]enerally moderate to severe/life-threatening", but while "[...] cats appear to be more sensitive to the effects of caffeine than people", "1-2 laps of coffee, tea or soda will not contain enough caffeine to cause poisoning in most pets [...]".

So you should be safe with the current situation, but please do be careful!

By the way, this is my first answer on pets - is that considered a reliable source around here? – BoBTFish Apr 9 '14 at 9:23
Yes, posting the source of your reference, allows others to make their own judgement on the reliability of the source. While I am not familiar with this source, it appears at first glance to be reliable. – James Jenkins Apr 9 '14 at 11:46

Caffeine is very bad for cats and dogs. Don't let your cats have any coffee, soda, tea, etc.

One tiny dose won't kill them, but you could be racking up organ damage each time. The HCCUA health website states that cats will get heart and nervous system damage from caffeine. I imagine it would also hurt the liver, kidneys, and GI tract as well.

Plants make caffeine to kill off any creatures eating the plants. Alkaloids (caffeine is an alkaloid) are intended to kill off anything that eats them, not just insects. Humans and other plant-eating animals have developed defenses to common alkaloids, which is why people aren't really affected by caffeine. Cats and dogs have no such defenses.

Also, from what I have read, caffeine is meant to kill off insects, rather than large animals. That is why humans aren't really affected by it, but with the right dose, caffeine can kill a human: – IQAndreas Apr 10 '14 at 10:40
