This kitten doesn't want to drink from her own bowl but seems to prefer running water, namely the waterfall of a hang on filter.

Is this safe for the kitten? The aquarium is occupied by a terrapin which is as far as I know. And if it isn't, how can I persuade her to drink from her own water bowl?

    Also of concern would be the health and wellbeing of the terrapin.... Aug 14, 2018 at 14:51

    I found that the location of the waterbowl can make a difference. Our cats wouldn't drink from it when placed near their food, but when we moved it to a different room, they did. The contraption on your picture looks like it's a combined food/water container, so that may be an issue.

This sounds like undesirable behaviour to me.

Here are the main problems in my mind:

  1. The cat could fall into the tank, damage the terrapin or tank, splash water on an electrical appliance, etc.
  2. Terrapins are known for being nippy. If it nips your cat you could open yourself up to any number of issues for both parties.
  3. The water in your fish tank may not be suitable for your cat. For example, you could need to use medications in the future which might harm your cat.
  4. Your cat could transfer bacteria to the tank which could adversely affect your fish tank and endanger your terrapin.

Okay, but what can I do?

I'd first put a lid or covering on the tank to stop the direct access that the cat already has. If this isn't possible because the filter would still be exposed, you can try training your cat not to go there.

If the cat really only likes running water, you can also get it a drinking fountain (This is the first one I found online - YMMV). The cat will be able to drink from a running water source without needing to disturb the aquarium.


The cat might also like the taste of the water. Some animals are quite the connoisseurs.

My dog prefers to drink "old" water from a big basin standing outside, one cat enjoys licking up the water puddles beneath my flower pots and the other cat prefers fresh tap water.

The chemistry of tap water differs so much from aquarium water that even you could probably taste a difference. Temperature and the material of the container also influence the taste of water.

Experiment with different containers (glass, plastic and metal bowl) and fresh and tepid water. The drinking fountain mentioned by Henders is also a nice try.


They sell fountains for cats. Basically, it's a water bowl (or basin) for the cat to drink from. The bowl is hooked up to a circulating system that keeps the water flowing. This is why your cat is attracted to the aquarium. Though many cats will drink still water, it's not uncommon for individual cats to be turned off by the idea. In the wild, still water could be stagnant or impure, so your cat's instincts may be leading it to seek out moving water.

A cat fountain can be purchased at most pet stores and will run between 30 and 80 dollars, depending on how fancy you want to get. Good luck!


I looked for fountains but couldn't find any locally that were suitable. I wondered what she was being attracted to as she didn't always drink from the waterfall.

So maybe it was the large body of water, the plastic, and no interference with her whiskers. So I tried a large stainless steel pan filled with tap water. Success!

Now to stop her from jumping out the 13 floor window onto the ledge :(
