DO monitor the situation

Before you act, watch the kittens from a distance. The mother cat is probably nearby. If she doesn’t return within 4-6 hours, they may need assistance.

DON’T move the kittens

Unless they’re in danger, it’s best to leave unweaned kittens outside so the mother cat can care for them. If you must do something, you can place the kittens in a crate, but do not change their location.

DO be careful when handling kittens.

Baby kittens have a developing immune system and you may inadvertently give them disease. Older kittens may not be friendly and may scratch or bite you if startled or scared.

DON’T panic.

If you are unable to care for unweaned kittens and they are truly orphaned, we can take them in.

DO volunteer to foster the kittens.

If you determine the kittens are orphaned and you decide to care for them, we can provide resources to make your experience successful.

DO keep orphaned kittens separated from your pets

This is to prevent fights and minimize the transmission of disease and parasites. Be sure your pets are up to date on vaccines.

DON’T let the cycle continue!

kittens under 4 weeks


For bottle feeding kittens (0-4 weeks old), it is ideal to keep them confined in a carrier or crate with a heating pad on LOW (heating pad should be under towels/blankets and not in direct contact with the kitten). Kittens need the heat to stay warm. As kittens grow you will increase their amount of space.


Formula: Bottle baby kittens eat kitten milk replacement (KMR), which can be purchased at any pet food store or online, along with kitten bottles.

Directions for Mixing KMR powder: Gently stir or shake one part powdered KMR into two parts warm water (a part may be a teaspoon, tablespoon or cup). Do not mix more KMR than can be consumed in 24 hours. Do not use a blender. Be sure the formula is lump free! Reconstituted KMR should be kept refrigerated.

Position: Lay the kitten in a natural, belly-down position — never, ever on his/her back. Gently slide the bottle into the kitten’s mouth and slowly drip formula onto the tongue. The kitten should begin to swallow. Very slowly continue to drip formula into the mouth. If the kitten latches on and is suckling, that’s great! Just make sure that she isn’t eating too quickly; help the kitten keep a slow and steady flow.


Kittens aged 0-4 weeks old will need help eliminating. You can use baby wipes, a warm, wet washcloth, tissue, or gauze to help stimulate their genitals. Rub the material in a circular motion on their stomach and move down to their genitals. It may take lots of tries and effort to get them to go! If you need some support, check out Kittens should be stimulated before and after every feeding.


At 4 weeks old, kittens can be transitioned to using a litter box and eating wet kitten food. Place a shallow litter box near them and watch them figure it out! Introduce wet kitten food by making it available in a shallow dish or placing it in their mouth. Continue bottle feeding KMR as needed. When the kitten reaches 2 pounds (approx. 8 weeks), contact Pasadena Humane Society & SPCA for a spay/neuter appointment.
