warning: incompatible Objective-C types assigning superClass to subClass

Question
Assume a valid super class, and a valid subclass ie the classes work.
the following line in a constructor of the subclass self = [super init] ;
throws the following warning // warning: incompatible Objective-C types assigning 'struct Animal *', expected 'struct Cat *'
Any ideas on how to fix this and remove the warning ?
Cheers
Solution
Do you provide a custom init-Method in your superclass?
Check the return type of this method. Is it (Animal *)? If so, change this to (id).
Init methods should return (id)
