Curb Cat Suckling
Q: I have a spayed 8-month-old mixed-breed cat. She is obviously mixed with Persian because of her huge fluffy tail. Her problem is very strange to me.  Her chosen way of showing affection is sucking and biting my hands or arms. She wants to do this when we are playing in the morning and when I'm looking at TV at night with her on my lap. Have you ever heard of it before, and have you any suggestions to cure this behavior? 

A: Sucking and kneading are instinctual behaviors that all kittens must do in order to nurse. Kittens usually nurse until they are 4-6 weeks old, then mom weans them and they transition to eating solid foods. Sometimes the mom will let kittens nurse longer, for comfort and reassurance. Kittenhood is the time where kittens who are lucky to be with their mother and siblings feel the most protected and safe. Mom keeps them warm, secure, well-fed and out of harm's way.

Many cats who were taken away from their mother and bottle-fed or weaned too early will suck on their human companions or on fabrics. It’s a comfort behavior, typically accompanied with purring, and is usually done when cats feel safe, secure and content. Some of these cats will suckle on their own tails or other parts of their body. I have a 7-year-old cat who suckles on his right dew claw whenever he curls up next to me on the sofa.

There was an online survey that was conducted on cats who suckle as adults. Based on responses, the conclusions were that cats who suckle as adults most likely were separated from their mothers and siblings at 8 weeks old or younger. It  also concluded that most of these cats suckled throughout their lives, though some of the cats suckled less frequently as they aged.

Because having your hands and arms suckled on isn’t the most ideal situation for you, gradually transfer the behavior on to a safe object that your cat can not ingest. There are cat-safe toys that will work. Make sure that the new object doesn’t have eyes, noses, whiskers and other pieces that can be chewed or sucked off. Also, the fabric needs to be a nontoxic substance that the cat can’t ingest. I know someone who transitioned her cat so he would suckle on a teddy bear. Before transitioning your cat to suckle another object, rub the object on your arms and hands, transferring your scent to the object. Whenever she starts suckling on you, present her with the preferred object. Be patient and gentle with her; with time she should suckle the approved object.

I watched our mommy kitties claw and hiss at the baby kitties when they are done nursing them, they are no longer allowed to knead or suck. So there is a time they are forced to quit. If you are now their mom then you need to do the same thing, make them stop just like their real mommy does. If you continue to allow this behavior then they will never stop and if they insist atleast they know you don't want them to do it and won't do it as often.

Two abandoned kittens, one at roughly 4 months, the other slightly older, came into my household recently. They took well to solid food as that was the only thing I had at the time. The younger ome,, suckles on the older ones arm, and they cannot be separated or they both enter a state of anxiety. It is quite adorable, and I'm glad to have them, even if the younger one is a bit of a brat.

My 4 month old kitten was found abandoned within a couple hours of birth in a parking lot with a 8 inch umbilical cord still attached to her. She was so small, not much larger than a large peanut, and she was trying to crawl out of the hot sun across the hot asphalt with cars buzzing out of the lot around her. It was by chance I heard her little whines. I scooped her up and I nursed her on my leg for 3 days by making a shallow pool of kitten replacement milk for her to lap up until her mouth was big enough for a small bottle nipple. She moved onto solid food by Day 28 and now she suckles, purrs and kneads every chance she gets with me. She's very content and I am happy! She is the best little baby I've ever had, I named her Vita!

I have a Calico kitten, she is 51/2 months and just start to suckle on her own paw or her brothers paw. I don't like it and really hoping she will stop this behavior. Kitten was hand fed at about 5 weeks. Her mother fused to feed kittens.
