What are the signs that my hamster needs a bath, and how should I give it?

Hamsters rarely need baths and can clean themselves. However, if your hamster gets into something sticky or dirty, you can offer a sand bath with chinchilla sand. Avoid water baths as they can cause stress and hypothermia. If a water bath is absolutely necessary, use lukewarm water and a mild pet shampoo, ensuring the hamster is dried thoroughly and kept warm afterward.
