The transparent spot under the display is often a fingerprint sensor or a camera. In some cases, it may also be a light sensor or a proximity sensor. The purpose of this transparent spot is to allow the device to capture or sense information without obstructing the display. This design allows for a seamless and unobstructed viewing experience while still incorporating necessary features. **

The transparency of your nail at a certain spot could be due to a variety of reasons. It could be a result of trauma or injury to the nail bed, causing the nail to become thinner and more transparent in that area. It could also be a sign of a fungal infection or a deficiency in certain vitamins and minerals. If you are concerned about the transparency of your nail, it is best to consult a healthcare professional for an accurate diagnosis and appropriate treatment. **

Spot-on treatments for cats should be applied according to the instructions provided by the product manufacturer. Typically, spot-on treatments are applied once a month to prevent and treat fleas, ticks, and other parasites. It is important to apply the treatment consistently and regularly to ensure its effectiveness. Additionally, spot-on treatments should be applied to a specific area on the cat's skin, usually between the shoulder blades, to prevent the cat from ingesting the product while grooming. **

No, the cat did not lick off the spot-on treatment. The spot-on treatment is designed to be applied to the skin at the back of the cat's neck, making it difficult for the cat to reach and lick off. Additionally, spot-on treatments are formulated to dry quickly and have a bitter taste to discourage licking. It is important to follow the instructions for application carefully to ensure the treatment is effective. **

Spot-on treatments containing ingredients such as fipronil, selamectin, or imidacloprid can also help dogs against mites. These ingredients are effective in killing and preventing mites, including sarcoptic and demodectic mites. It is important to consult with a veterinarian to determine the most suitable spot-on treatment for your dog's specific needs. **

After a spot-on treatment, fleas typically die within 24-48 hours. The active ingredients in spot-on treatments are designed to quickly kill adult fleas on the pet's body. However, it's important to continue with regular flea prevention measures to ensure that any new fleas that may come into contact with the pet are also eliminated. Regular use of spot-on treatments and other preventive measures can help keep fleas under control. **

I recommend using a spot-on flea treatment specifically designed for cats, such as Frontline Plus or Advantage II. These products are safe and effective for treating and preventing fleas on cats. It's important to follow the instructions carefully and apply the treatment to the back of the cat's neck, where they cannot lick it off. Be sure to consult with your veterinarian before using any flea treatment on your cats to ensure it is appropriate for their individual health needs. **

There are several spot-on flea treatments that are suitable for two cats, including Advantage II for Cats, Frontline Plus for Cats, and Revolution for Cats. These treatments are designed to be applied directly to the skin at the base of the cat's neck and provide long-lasting protection against fleas. It's important to consult with a veterinarian to determine the best option for your cats based on their individual health needs and any potential interactions with other medications they may be taking. **
