When you've been selected to feed a litter of kittens, this is all you need, plus a lot of time.
Mix some cream with Cat Milk, suck it up in the syringe and squeeze very slowly into the mouth of a hungry
Be careful not to drown any of them and after a few days, they'll start to suck just like a baby with a bottle. Whiskas Cat Milk alone is not good enough, but add some cream and you're set. Just don't take pictures of the orphans......they look like fuzzballs with big bellies and sticks for legs. After two weeks, bring out the camera, because they do get cute again.
