Our last cat (now deceased) would ONLY drink from a running water faucet for her last few years. It didn’t matter how many bowls of water we left out for her, she INSISTED that she had to have water fresh from the source–notably our bathroom sink.
We now have two new cats who are definitely obsessed with water.
Cat A is a big, fat, long-haired cat we found as a stray, probably ~3yo. He is very lazy, and when we first got him, his favorite way of obtaining water was to plop down in a reclined position relatively close to a water bowl, then use his paw to pull the bowl within reach of his tongue.
Cat B is a high-strung, short-haired cat, who acts like she is afraid of EVERYTHING. However, she is one of those cats who drinks primarily by dipping her paw completely into the bowl of water, and licking the water off her paw. She will drink straight from the bowl, but only after she’s gotten tired of licking water off her paw. OTOH, she gets really grossed out if she walks into a wet shower and gets water on her paws.
We left them alone for an extended weekend, and bought a pet water bubbler to make sure that they had plenty of water while we were gone. For those who aren’t familiar with this product, it’s essentially a bottle of water that is inverted over a bowl, and it can provide up to a gallon of water at a time. However, once the water level drops down a bit, bubbles bubble into the bottle, making a loud burbling noise.
The first few times the water bottle burbled at the cats, they ran for their lives–it was hysterical. Cat B is still not too sure about the safety of this device, but she will drink from the bowl of water if it is the most readly available source of water. Cat B, however, LOVES this thing now. He will lie down at the bowl of water, and literally drink until it burbles at him, regardless of how much water he has to drink until he gets to that point. When I refill the bottle, it burbles for a good ten minutes until it finally reaches the “full” level in the bowl, and he gets very excited sitting in the bathroom watching it burble whenever I refill it.
Cat A also LOVES to watch toilets flush, and has occasionally reached his paw in to try to grab stuff floating as it swirls around. Cat B watched the show a few times, but has lost interest in the last couple of months.
