What Causes Cat Dehydration?
1- Dehydration can occur in cats for a variety of reasons. One of the main reasons is that it is in their genes. Felines evolved from desert dwellers, so they have a lower thirst drive and can survive on less water than canines.
2- Cats have poor near-sightedness, so it may be difficult for them to see the edge of the water in a bowl. Furthermore, when cats lap water from a bowl, their tongue curves into a J-shape and bites off a column of water, which is extremely inefficient. Cats only get 3/100 of a teaspoon per lap!
3- Cats are also sensitive to the taste and appearance of water. Most cats are drawn to fresh, moving water instinctively.
4- Chronic kidney disease and other conditions such as diarrhea or diabetes make cats more prone to dehydration.
