The urine of a normal pet cat was dropped onto the granules prepared in Example 1-5 of the disclosure, which was used as a control group to observe color changes. Take pet cat urine with protein content of 0.1 g/L albumin, 0.15 g/L albumin, 0.3 g/L albumin, 1.0 g/L albumin, and 3.0 g/L albumin and drop them onto the granules in Examples 1-5 as the experimental groups, and observe the color changes. Add tap water dropwise onto the granules in Examples 1-5 as a blank group, and observe the color changes. The results are shown in Table 1.

As shown in Table 1, it can be seen that the granules for protein detection in pet urine of the disclosure respond quickly, with prominent color development and long color persistence. When the pet urine contains protein, the granules will turn blue, and when the experimental sample is normal urine or tap water, the color will not change. Therefore, the granules for protein detection of the disclosure can quickly and accurately detect whether the pet urine contains protein, thereby determining the health status of the pet.

It will be obvious to those skilled in the art that changes and modifications may be made, and therefore, the aim in the appended claims is to cover all such changes and modifications.
