The first step in helping kittens you see outside is assessing how old they are and determining if and when to intervene. Alley Cat Allies’ How Old is that Kitten is a great resource in estimating the age of kittens. Once you understand the kittens’ age, you can decide how to help them.

The Socialization Process

If you are planning to adopt out kittens or get them into a shelter, it is critical that they are well socialized. Kittens must pass a behavioral exam during the shelter intake process whereby they are handled by veterinary staff that are meeting the kittens for the first time. If the kittens are terrified, hiss at the clinic staff or try to run away, they will likely be returned to you.Before you decide to take kittens into your home, please refer to What to do with Kittens to determine if they are an appropriate age to come inside. Kittens that are older than 12 weeks that are entirely feral should be TNR’d and returned to their colony, as they will be very difficult to socialize.

Set-Up

It is very important when bringing kittens off the street into your home to socialize them for adoption that you have the appropriate set-up. You will need a small space isolated from other pets where the kittens feel comfortable and you can have productive interaction with them. A small bathroom works well. If you are using a den, bedroom, basement or any other room, you should plan to start them out in a large wire dog crate (42” or 48”) on top of a table. This way you will have arms-length access to them and can sit in a chair in front of the crate, so you aren’t scaring them by towering over them. If the kittens are little, make sure that they can’t squeeze through the bars. You may need to fortify the sides of the crate with cardboard and wire ties. If your only option is to have kittens loose in a room, you need to clear out any furniture or other objects that they can hide under. Kittens that are hiding are not socializing. Kittens that are not socializing will remain feral and unadoptable.The younger kittens are, the easier they are to socialize. Every day that they grow older becomes more and more difficult. Do not wait for kittens to get acclimated to a space. Begin to work with them immediately. Every day that you wait will just make it more difficult to socialize them.

Play Therapy

Kittens are very curious and playful by nature. Getting feral kittens to play is a great way to distract them from their fear of humans and get them to relax. A stiff rod toy with a small, light-weight ribbon or feather on the end is the best socialization toy. You should be able to drag the toy quietly in front of them without “throwing” it at them or scaring them. Toys that are too large or make noise are not effective. Start off by just getting their eyes to follow it. Then they will reach out a paw and hopefully begin chasing it.  While they are playing, keep talking to them in a soft, soothing voice. They will learn to associate the fun of playing with humans. Do not leave toys in the crate. Kittens should not be having excess fun without you. They will be fine. They can play with each other’s tails. You are not doing them any favors by spoiling them. Socializing is “tough love.” The best thing you can do for them is to socialize them quickly and get them into their adoptive homes. Each time you come into the room, sit down and play with them for about 20 minutes before you feed them. Drag the wand toy towards you to get them used to approaching.

Food Bonding

Growing kittens are usually hungry, which works in your favor because you can use food as a socialization tool. Do not leave food in the crate or room. If you are not in the room, the kittens should not be eating. Instead, you should bring fragrant canned food into the room each time you come, place it near you or in front of the cage, and encourage the kittens to approach you to eat. Make them eat in front of you. Talk to them in a soft, soothing voice while they are eating. You can start touching them on their backs while they are eating, to teach them that food (which they love) is associated with human touch.You can also start to feed them from a spoon, lick food off your fingers and take treats from your hand. Gerber’s chicken and gravy baby food works well as a special treat, as do “meat tubes,” which are pureed cat food in a tube-shaped wrapper. Visit them as many times a day as you have time for, play with them and feed them each time.

Next Steps

Once the kittens begin to relax and feel more comfortable in your presence, you can work on additional handling. Start by stroking their back, then scratching their head and cheeks. Move to petting them with both hands, then lightly squeezing them on each side, then lifting them about an inch or two off the ground, then higher. If you do this gradually, you should eventually be able to pick them up without them panicking. Work at their pace, but continuously push their comfort level. Remember that you are their ticket to a loving, adoptive home.

Other Tools

If you are the only person that interacts with the kittens, there is a chance they will only socialize to you. If you can, invite other people into your home to interact with them. Coach friends and family members not to scare the kittens and to be gentle and patient with them.A radio or television is a great addition, to get the kittens used to human voices.Also refer to The Best Friends Cat Socialization Guide and How to Socialize Hissy Feral Kittens from The Kitten Lady.
