Feline distemper virus is a highly contagious disease of cats with a high mortality rate. FPV cat plague detection needs to be based on control points and sample points. The control point and the sample point are the two most important parts of the cat plague detection card, and they are indispensable:

1. If both the control point and the sample point are displayed, it means the cat is positive for FPV.

2. If only the control point is displayed, it means the cat is FPV negative.

3. If neither the control point nor the sample point is displayed or the sample point is displayed but the control point is not displayed, it means that the test plate is invalid. When purchasing a test card, be sure to check the quality of the cat plague test card. If the test card is expired or of substandard quality, it may not be detected.
