A tall fresh glass may be more appealing in material, height or location than the cat’s bowl. Human drinks may contain caffeine, alcohol, sweeteners or other unsafe ingredients.
The short answer
A tall fresh glass may be more appealing in material, height or location than the cat’s bowl. Human drinks may contain caffeine, alcohol, sweeteners or other unsafe ingredients.
What to observe
Check which container shape and placement the cat repeatedly chooses.
How to read the situation
Human drinks may contain caffeine, alcohol, sweeteners or other unsafe ingredients. Compare the pattern with your cat’s usual behaviour and consider timing, body language, appetite, litter-box use, mobility and recent changes.
What to do now
Provide a dedicated wide stable glass-style bowl with plain fresh water and cover unsafe drinks.
What not to do
Do not punish, frighten, force or repeatedly test the cat. Avoid changing several things at once, because that makes the response harder to interpret.
When to contact a veterinarian
Any suspected alcohol, caffeine or toxic sweetener ingestion needs urgent veterinary or poison advice.
What to record
Write down when it began, how often it happens and what occurs immediately before and after. A short video, clear photo, food record or litter record can give the veterinary team useful context.
What to check first
Identify exactly what was in the glass and whether the cat drinks more overall than usual.

What to do next
Keep unsafe drinks covered and out of reach, offer a stable wide glass-like water vessel just for the cat and refresh it daily. Alcohol, caffeine, xylitol or medication exposure needs immediate veterinary or poison advice.
