Yes, cats may choose to give birth outdoors. They will usually look for a quiet, safe, and secluded place as their birthing bed, such as grassy areas, abandoned buildings, or hidden sewers.
This behavior may be due to the cat's lack of security in the indoor environment, or it may be their instinct driving them to seek a more suitable environment for giving birth and raising their kittens. If your cat is pregnant, it is recommended that you provide her with a safe and comfortable indoor environment to reduce the likelihood of her choosing to give birth outdoors.
