First, sleepiness. The cats you just bought are usually kittens. If yours happens to be a kitten, then sleepiness is normal. Just like children, they sleep every day in infancy, and so do cats and dogs. You don't have to worry too much. You should provide a clean, warm, comfortable and clean environment for your cat to sleep well. Second, ear mites. Cats have ear mites, preferably for external use, such as cleaning drugs and ear oil. Sarkin used to have cat ear oil, but now it's not sold. Unfortunately. The treatment of ear mites usually takes about a month. You should take the medicine according to the doctor's instructions and wait patiently. It is important to keep the environment clean, because what mites fear most is cleanliness. Third, the problem of insect repellent. Personally, I think cats are so small that it is barely edible to take anthelmintics to treat parasites in the body, but it is a bit unreliable to take anthelmintics to drive mites, because mites are under the cat's body surface and are no longer in the body, so it is more dangerous for cats to take medicine. Insect repellent is generally preventive, so it is best not to inject drugs or take medicine into cats. Just wear a cat collar. This Sargin's is still on sale.
