I purchased this in June 2025 to measure my dog's temperature. I have three dogs, a medium-sized dog and two small dogs. It seems there's a knack to taking their temperature, and sometimes I could measure it properly, and sometimes I couldn't. Therefore, I'm selling this because I bought another thermometer. I used the included lens covers several times, so I think there are only a few left. I'm including 40 new, separately sold lens covers (3200 yen on Rakuten). You can measure the temperature in 1 second by inserting it into the ear, so it's easy to take the temperature once you get used to it. I plan to ship it via Takkyubin Compact. Here is the product description from the purchase site: Fever. It's a sign that something is wrong with the body. Pets can't speak. It's our responsibility to notice. It's our love. Make it a habit to take their temperature for your precious family. ・A healthy dog's normal temperature is about 38°C to 39°C. Puppies and small dogs tend to be higher, while adult dogs, large dogs, and senior dogs tend to be lower. ・A healthy cat's normal temperature is about 37.5°C to 38.5°C. Kittens tend to be higher, while adult cats and senior cats tend to be lower. This thermometer is for pets (animals) only. It is specially designed to fit pets' ears. It is suitable for dogs, cats (including puppies and kittens), rabbits, ferrets, guinea pigs, chinchillas, hamsters, ferrets, and most companion animals. ■Wannyann Pet Electronic Thermometer Pet-Temp ■Set Contents ・Thermometer body ・Dedicated case (drawstring bag) ・Lens cover (20 pieces) Disposable, for one-time use ※After using the lens cover included with the main unit, please use the separately sold "Lens Cover LC-40" (40 pieces). ■Size Body: Approximately 13.5cm x 6.5cm x 2.8cm Arm length: 8.5cm (from the tip to the bend) ■Material: ABS resin (exterior) ■Model: PT-300 ■Built-in 3V lithium battery (approximately 5 years of normal use) ※The battery cannot be replaced ■Measurement site: Tympanic membrane surface and bony external auditory canal ■Measurement temperature range: 34.0°C to 43.0°C ■Measurement time: 1 second Astec Co., Ltd.
