All pets should drink water daily. Most dogs and cats should have ready access to water. This should be at a spot in their home where they feel comfortable drinking without being harassed or otherwise disturbed.
Water consumption is also important for cats and dogs with kidney problems and arthritis. An arthritic pet often has wear and tear in their joints that results in pain.

Studies have shown that onega three fatty acids can benefit older cats that have reduced mobility due to arthritis. It decreases their discomfort.
