Why Is My Kitten So Cuddly?

There are a number of reasons your kitten may be so cuddly. Some cats have more sensitive stomachs and they’ll prefer to lay on soft surfaces, such as pillows or blankets. Some kittens will cling onto their momma cat because she is the one who feeds them. In this case it would behoove you to find a friend who has an available bed for your kitty! A new mother can become very possessive over her cubs and those little babies feel safer in close proximity with their own kind, especially if there are no other puppies around.
