If they're both healthy, it's fine for them to drink out of the same bowl. However, cats might not like sharing a bowl, and they may stop drinking in protest. They also might not like the typically larger size of a dog's bowl. It's best to leave out separate bowls in different places for your dog and cat.
In the wild, cats eat and hunt alone. They are wired to be protective of their food. Forcing cats to share bowls at home may result in cats eating too quickly, guarding bowls, or fights. Feeding cats from separate bowls also allows you to give different portion sizes and diets.
However, it's important to know that cats are typically much more territorial than dogs, so don't be surprised if your cat isn't too keen on the idea of sharing a water bowl. In fact, this might even deter your cat from drinking water and lead to dehydration, which is a serious health threat.
Of course they can. I have 6 cats who share 2 water bowls without any issues. Just make sure the water is separated from the food. Cats in the wild will not kill their prey near water so the water doesn't get contaminated.
It can be usually common for some cats to eat from the same bowl but not every pet owner would allow that, considering this can cause conflicts at times. Cats that live together can be friends and share food with each other, but some owners do not want their cats to eat out of the same bowl.
Follow this simple rule: one box per cat, plus one extra. So if you have two cats, you should have three boxes. Making sure everyone has their space can help ease elimination issues. Some owners prefer a hooded box, but some cats don't like them.
Where should I put my cat's water bowl? Just like their food, your cat's water bowl should be somewhere relatively quiet. A hallway, for example, may be too busy for them, even if they are very sociable. Put your cat's water bowl somewhere clean and odour-free – and far away from their litter tray!
Cats are biologically programmed not to drink water which is near their food or near their toileting area - this is thought to be their instinctive avoidance of contaminating their water with potential sources of bacteria.
In the wild, cats know to keep their prey – their food – far away from a clean water source. They know that their prey could contaminate their fresh water source. This is why feline behaviorist and vets recommend keeping the water bowl far away from a cat's regular meal spot.
The bowl causes "whisker stress."
Whiskers are special "Tactile hairs" called vibrissae with extremely sensitive follicles. These sensitive whiskers compensate for a cat's poor eyesight.
Give your cat a clean cat food bowl EVERY SINGLE DAY - either wash your cat's bowl daily or have extra bowls on hand. If your cat is on a raw food diet, consider giving your cat a clean bowl after each use. Change your cat's water each day and swap out your cat's water bowl daily or at least every 2 days.
If you have multiple cats, they may be comfortable enough with each other to share the same litter box. However, there are several reasons, including territorial behavior, why some experts would advise at least one extra litter box in your home.
Cats with dental infections, inflammation in the mouth or gastrointestinal disease may avoid drinking water due to the discomfort it causes them. Cats with underlying health issues may be more likely to become dehydrated, especially those with kidney issues, hyperthyroidism, some cancers and diabetes.
Communal feeding is convenient for us but can create mealtime tension and competition for cats. The key is to provide separate, small food bowls for each cat. I recommend separating the bowls by at least two feet to lessen the impact of any menacing stares.
For some cats, separation anxiety may lead them to splash in the water dish, push it aside, or try to overturn it to get your attention. Obsessive-compulsive disorders can become worse with stress as well.
Cats sometimes prefer drinking water that is cold, because they might perceive cold water to be fresher. Keep your cat's water cold by replenishing it regularly. You could even pop a few ice cubes in the bowl if the weather is particularly warm.
Running Water Tastes Better
Just like us, running water from the faucet may tickle your cat's tastebuds more than the stale, dusty water in their bowl. “Cats, like all of us, prefer fresh cool water,” Wieber says.
One suggests that because the species evolved in dry climates and had little exposure to rivers or lakes, water (except for drinking) is an element they are unfamiliar with and thus avoid. More likely, however, cats don't like getting wet because of what water does to their fur.
In most cases, experts say giving your pets hard water probably won't cause any problems. The minerals in hard water (calcium, magnesium, and iron) shouldn't lead to any health issues. However, some veterinarians do advise against giving cats and dogs untreated tap water, and that's not because of the minerals.
The best type of water for cats is filtered tap water. It's safe, easy to access with a simple pitcher filter or faucet attachment, and guaranteed to be pure. That said, most types of water are fine for cats to drink.
If you have a young cat at home and want a second, consider adopting one kitten of the opposite sex, as same-sex cats are much more prone to fight each other for dominance. Your resident cat will still be young enough to recall having fun with her littermates, and the new kitten will be more than happy to oblige.
Pairs are Happier
Despite their independent natures, cats are social creatures that need companionship to thrive. Left alone, a cat can develop behavioral problems, and in some cases, even show signs of depression. Cats in bonded pairs, on the other hand, are more likely to be better adjusted.
Cats are family-oriented and usually live with their relatives. Cats will sleep together, share common feeding areas, and groom one another within family groups. For this reason, cats often do well adopted in pairs.
