How Big Is a Nesting Box for a Cat?

You should prepare a delivery box, also called a queening, nesting, birthing or kittening box, at least two weeks prior to delivery so your cat has time to become familiar with it.

  1. Type of Box

    • Mary Anne Miller, writer and member of The Cat Writers' Association, says you can make your own or use many other items as a delivery box. You can use a cardboard box, carrying crate or kennel, dresser drawer, large plastic storage box or even a large clean litter box. Peteducation.com recommends you use an easy-to-clean box. If you decide to use a cardboard box, have replacements handy so you can swap out the box if it becomes soiled or torn.

    Box Size

    • Paw Prints and Purrs, Inc., says the box needs to be big enough for the cat to move easily. Measure your cat from nose to tip of outstretched tail to determine an adequate size box. The sides should be high enough, about 6 to 8 inches, so the kittens cannot get out when they are babies but not too high for the cat to jump in and out.

    Extras

    • Most cats prefer some type of cover on the box or seclusion, such as in a closet. Miller recommends soft layered bedding and air holes cut in the sides if you use solid rubber or plastic boxes.

    Box Location

    • Place the box in an area where it will be undisturbed, quiet, dark, warm and away from drafts.

    Tips

    • Have plenty of extra bedding to replace soiled ones.
