My 6 mo. old kitten developed such a bad hairball it was blocking her intestines. I've had cats cough up hairballs before but never one that was life threatening. She was pulled through at the vet's with massive doses of cat lax and fluids to help rehydrate her.
I was using a really good brand of cat food, but I switched all my cats to Purine One Special Hairball formula after reading that soy lecithin will help break up the fat that binds the hairball together. The soy lecithin made sense and a better way to go than forcing vaseline type stuff down 5 cats. I plan on going back to my original brand of cat food and sprinkle soy lecithin granules in soft food and/or chicken baby food on a regular basis in addition to their regular dry food.
BTW, any one that has a cat with FUS can help unblock their cat with 500 mg of Vit C. Use it until the cat is unblocked and then follow up as often as you feel necessary to keep your kitty clear. I mix the proper amount of powdered Vit C with chicken baby food. Do not use more than 500 mg in one day and do not use Ester C.
Hopefully passing this along might help some one.
