Kittens with a room temperature of 18℃ are generally not cold, but if the kitten is too young or has short hair, it may be infected with cold. Kittens will tremble, curl up, cling to others, and hide when they are cold. If this happens, you need to pay more attention. It is best not to let the kitten stay in a relatively low temperature environment for a long time to prevent the kitten from catching a cold.
Tip:
If the kitten feels cold, you can turn on the air conditioner or prepare a blanket and cat bed.
