1. Field of the Invention
This invention relates generally to drinking water and hydration and particularly to flavored drinking water additives, flavored drinking water compositions and methods for increasing water consumption and improving hydration for animals, particularly felines.
2. Description of Related Art
Hydration is essential to a cat's health. Water aids in waste elimination, body temperature regulation, and digestion. However, in the wild, they typically derive most of their fluid needs from the prey they consume. Ensuring that a cat has sufficient water intake is a common problem for cat owners. A flavored water additive is a convenient vehicle for enhancing drinking water for cats.
Palatability enhancers for pet food are known in the art. U.S. Pat. Nos. 6,354,920 and 6,350,485 to Brunner disclose the use of tetrasodium pyrophosphate as a palatability enhancer for dry and semi-moist cat food. U.S. Pat. No. 5,186,964 to Gierhart et al. discloses the use of a pyrophosphate salt or an acid phosphate salt as a palatability enhancer for dry pet food. U.S. Pat. No. 7,244,460 to Lee et al. discloses the use of a tripolyphosphate salt as a palatability enhancer for dry and semi-dry pet food. The use of a palatability enhancer as a flavored drinking water additive is novel.
Many pet owners, particularly cat owners, believe their pets do not drink enough water. There is, therefore, a need for new flavored drinking water additives, flavored drinking water compositions and methods for improving hydration for animals
It is, therefore, an object of the present invention to provide flavored drinking water additives.
It is another object of the present invention to provide flavored drinking water compositions suitable for consumption by animals.
It is another object of the present invention to provide methods for increasing water consumption by an animal.
It is another object of the present invention to provide methods for improving hydration for animals.
One or more of these and other objects are achieved using flavored drinking water additives and flavored drinking water compositions to provide methods for increasing water consumption by an animal or improving hydration for an animal. Kits comprising combinations of flavored drinking water additives, vitamins, minerals, functional ingredients, and devices useful for promoting the health or wellness of an adult animal are also provided.
Additional objects, features, and advantages of the invention will be readily apparent to those skilled in the art.

The invention can be further illustrated by the following examples, although it will be understood that these examples are included merely for purposes of illustration and are not intended to limit the scope of the invention unless otherwise specifically indicated.
Four (4) flavored water additives (labeled A1, A2, A3, and A4) were made by blending and mixing the dry ingredients shown in Tables 1 through 4. All additives were soluble in water at the ambient temperature (23° C.).
Four (4) flavored water drinks (labeled B1, B2, B3, and B4; referred to as a group as “test drinks”) were made by dissolving the flavored water additives in tap water in the amounts shown in Table 5. Saline was used as a control.
A group of sixty (60) cats were offered the test drinks and the control at the same time for a period of four (4) hours. A two-bowl feeding test methodology was used. The drinks were randomized with the test drinks and control drink placed on the right-side bowl or left-side bowl. Standard dry cat food was also provided to simulate a home water consumption environment. At the end of the 4 hour period, drinking amounts of each cat for the test drinks and control drink were recorded. Consumption % was calculated as the ratio of drinking amount for one drink over drinking total amount for two drinks. Individual animal consumption data were then averaged to determine the average consumption %. Statistical analysis was performed and p-values for the difference between the test drinks and the control were calculated. The results from six (6) repeats of the experiment are shown in Table 6.
A group of sixty (60) cats were offered a test drink and a different test drink the same time for a period of four (4) hours. The experimental procedure in Example 2 was repeated. The results from three (3) repeats of the experiment are shown in Table 7.
Example 3 was repeated using the saline control and tap water without added saline. The results are shown in Table 8.
Referring to the Table 6, the results show that cats had significantly higher consumption of flavored water drinks (test drinks). All p-values are less than 0.05, which indicates the palatability difference between the flavored water drinks and the control drink was statistically significant. Referring to Table 7, the results show that cats had significantly higher consumption of flavored drink B4 presented in saline than from saline alone; and that cats had a higher consumption of flavored drink B2 than B1. Referring to Table 8, the results show that cats had equal consumption when they were presented with Saline and Tap Water at the same time.
