Poll: Is Your CH Cat Smaller Than Average?
After receiving Ruth’s book in the mail, Lauren realized that her Mimosa and Ruth’s Betty have something, other than cerebellar hypoplasia, in common: Both of their cats are on the smaller side.

Here you can see how Ellie (left) has a wider hind-leg stance than CG (right). This helps her keep her balance.
As Lauren put it, Mimosa, who recently turned two, is a tiny cat considering she’s a full-grown adult. She’s barely 8 lbs., and Lauren says her paws are the size of quarters.
This is something that I and a number of CH cat parents have wondered about from time to time, so I wanted to ask all of you — do you consider your CH cat to be smaller in size and weight than an average cat?
To answer that, we’d need to know what an average cat’s size is (based on weight). When researching this, I was reminded that an “average” cat can vary from 7 to 20 lbs depending on the cat’s breed and age. That’s a wide range, which can make this question and answers rather subjective. Regardless, I’m still curious what you all think.

For a while I’ve thought about why some CH cats may be smaller than other cats, and I’ve came up with a few ideas. Please chime in with your own thoughts, too!
1) Cerebellar hypoplasia is commonly caused if the mother cat contracts panleukopenia (distemper) or if there was some sort of trauma to the unborn kittens. While I’m no vet, I would imagine that either scenario, as neither one is ideal, may have additional impacts on the kittens. Perhaps they may not grow up to be as big and strong as they could be given their prenatal conditions. Perhaps there were other contributing factors (that don’t manifest like CH) that could have also impacted the kittens in other ways.
2) Along those same lines, I’ve wondered if kittens with more severe cases of CH turn out to be the runts.
This theory of mine was turned on its head when we adopted Ellie. She was the smallest of three (named Shadow because her foster thought she had a shadow of a chance to live), but as she grew older, it was apparent that the so-called runt actually had the least-severe case of CH among her siblings. Granted, Ellie is definitely moderate, while her sisters at the time were moderate/severe and severe.
That said, our one-year-old Ellie is a small cat, especially compared to CG.
What do you think? Do you think that a cat’s CH may be correlated to his size? Or do you think size is an independent factor?
My CH Kitty, who was moderate when he came to us, then got much worse, and now, thanks to a wonderful homeopathic vet is 100% better & back to “relative” normal – and he is a little chunker, although not unhealthily so. His appetite has increased as he’s gotten older & he especially loves sardines, which were recommended by our vet. BTW, as an aside – I was reluctant to go to this homeopathic vet as I was concerned that it would cost A LOT more – and it absolutely did not. The vet is wonderful & the recommendations he made for Little Man’s diet have helped immensely, along with the homeopathic meds we have him on 2x per day, (which are not any more expensive either) – so if you have access to one, I highly recommend them!!!!
My Wallis is very petite! he also has tiny teeth almost like baby teeth even though he is 4 years old..any other CH cat have this?
My CH kitten, BillyJack, is 4 months old and according to the vet he is about a month behind in growth develoment and even futher behind in teeth develoment. I have often wondered if there was a connection.
My Sally was almost a year old before she got all her teeth in, then within a month of turning one she lost her bottom left fang. Also her two top fangs grew in pointing forward instead of down, at least it doesn’t hurt quite as bad when she bites us. She is also on the small side about 6 pounds at two years old.
Shiloh, my first CH kitty was an average size cat, Tardy was average, although he did loose a lot of weight when he got older, Ziggy was too small for his age when we adopted him, but neutering and free feeding turned him into an average size, maybe a little heavy : )) Luna Süna and Spike are just 16 weeks now, so time will tell : )
I’m inclined to think size may be independent, though possibly if fighting infection, nourishment in utero might be going to fighting illness rather than growth, I took two non-CH runts, the tiniest who I frankly didn’t expect to live is now a normal chunky cat of average size – about 11lb – and the other, who had a mother complex to all her siblings, is no larger than a 9 month kitten-cat, barely 8lb. [she’s still the boss by the way]. There’s a lot of factors in this, I know that studies have been done with humans and in utero deprivation can lead to undersized adults and it can also lead to obesity if the opportunity is there as the body tries to overcompensate. I’m pretty certain that the reasons will be found in the pre-birth conditions but what exactly causes this may be a very complex subject. I hope you don’t mind me giving my cats stats as they are not CH but I have wondered before why one runt grew and the other didn’t. [not that either of them came close to their brother in size who was not a runt and who was bidding fair to be a stone of muscle and sleekness when he met with his fatal accident. Boys don’t seem to gain their full weight until they’re about 2, I’ve noticed, girls have just about finished growing at 1 year. Neutered cats WILL grow larger than unfixed too. Growth’s a complex business and it’s interesting to see some empirical research.
From Tammy:
Both of my CH cats are smaller than our other cats. Our eight “normal” cats all tip the scales at a range of 12 pounds to 18 pounds. Boo Boo only weighs 7 -1/2 pounds and little Faith is our tiniest cat at 6 pounds and she’ s going to two years old.
I always read about CH cat parents asking about headgear to protect there cat. I came across a web site that have them for cats and dogs and just wanted to share in case someone is interested its PoshPuppiesBoutique.com Good luck.
I found this site researching whether or not my adopted Kitty with cerebral hypoplasia could run on the smaller side because of his disorder. Although he is normal weight even a little stockier he seems to run height-wise on the north on the small side.
I met a ch cat in a no kill shelter . She is the size of a one month old cat and is six months old . She hides from the other cats. And sleeps . She when I picked her up put her nose in my colloerbone and purred loudly . Her eyes are almond shaped. She wanted to cuddle and was relieved to be held. Some of the cats lick her in affection none hurt her most ignore her. She seems to have trouble focusing her eyes and the more she try’s the more her head bobbles. She listened to the heartbeat in my neck. With great interest . She was intent on this . I don’t know why . She licked my palm.
I was there to pet cats whom lack human friends to seek out. I’ve three cats and a dog that is my daughters service dog . So can’t have another l I just like petting them is all, so I do . It is just this side of heaven on earth to go there and pet so many kitties
Our CH car will be 2 years in a month. He never grew to 3lbs. Every weigh-in we always guess he had finally made to 3lbs but we are always wrong. He has stayed at a constant 2.8lbs. I haven’t heard of a car so tiny. He is like a 10 week old kitten. Just wondering if there are other tiny ones.
We have a kitten with CH and she has always been smaller than her siblings. She looks like a tiny version of a full grown cat. I thought she was just a runt at first and wasn’t getting enough to eat (bottle fed her since she was 2.5 weeks old) but she never caught up and then we noticed her wobbling when she was walking. When she gets excited or in “pounce mode” her head shakes pretty fast, but for the most part she only drops her rear end and sashays a bit when she walks. Seems fairly mild from what I’ve seen and read. She’s our Sweet little wobbly midget kitty.
My cat with CH is quite a big boy. He was actually the largest from his litter, according to the pics his foster mom sent me of him with his siblings as kittens. He’s a large cat at about 15 lbs of charm and fluff!
