i weaned my kittens onto it - plus as Sungold has said the cimicat or lactol (that one is available at pets at home)
the kitten hi-life is 60% meat and considering my lot had problems with tummys on the RC babycat (some do, some don't) they had no problems on the hi-life xx

what you do weaning wise is start off with more milk to food ratio, then by 3-4 days later start to raise the food content and less milk on a gradual basis until they're on full solid x some i found were more interested in the meat, some more interested in the milk - but they'll all get there xx you should be able to judge by if theyre just lapping milk or if theyre chewing the food to whether they're ready to go to the next level xx
