How to quickly get rid of fleas on your cat in summer:
1. Use lemon juice. Mix lemon juice with an equal amount of warm water, then spray the diluted lemon juice onto the cat's skin to kill fleas.
2. Use orange peel juice. Don't throw away the orange peels after the cat has eaten the fruit. Use a tool to squeeze out the sour and bitter juice from the orange peels. Be sure to stir the juice evenly in boiling water, let it cool, and then spray it on the cat. This can effectively get rid of fleas.
3. Give your cat apple cider vinegar. Pour a certain amount of apple cider vinegar into your cat's drinking water. After the cat drinks the water with apple cider vinegar, the apple cider vinegar will seep into the cat's skin, and fleas that are afraid of acidic substances will naturally stay away from the cat.
4. Using rosemary sprig water to bathe cats can also effectively remove fleas. Boil fresh rosemary sprigs and soak them for more than half an hour, remove the leaves and stems, and let the rosemary sprig water cool before bathing your cat.
5. Use an appropriate amount of floral water. Floral water has antibacterial properties, but the scent is quite strong. Therefore, when using floral water to treat fleas on your cat, be sure to use an appropriate amount or a small amount.
