To many humans, socializing is a part of life. If you are a human, what do you usually do with your friends to socialize? Sure, kittens can’t get coffee or drinks. They can “get food!”
Usually, young kittens do not have much difficulty socializing, but older kittens (with little positive human contact) can be a lot harder to socialize. Not all cats are created equal, but these techniques can help your feline friend.
Growing kittens already have a big appetite, so work off of that fact. Possibly, make kittens interact with you to get their reward (their food). Pull their food dish as close to you as possible, and stay with the kittens until they are finished eating. When they are finished, pull the dish away with you. Remember, always leave water out for them.
After that, create body contact with them while they eat. Possibly, it would be good to pet them gently around their head and shoulders while they snack. You can also place a dish of food in your lap and let the litter to climb in to get it.
After a short time, you will be able to pick them up. Usually, picking them up low to the ground and moving them between dishes will not impact them when they are hungry. Although, all cats are different. Do what you feel is comfortable for you both.
Happy socializing!
