Animation wise do not expect this to be of the highest order - this is fine enough I reckon for the time it was made. Also this never reaches a standard that was set by Pixar (and others for that matter) - it is just family fun! Although to be fair that is not meant to be a bad thing.
Not every movie can reinvent the wheel - and in this case if you want a movie about pets who are into adventures, you could do worse. Also a bunny that is jealous and sort of bad behaving? It might have been done similarly before, but I do not remember an instance to be honest. So there are some unique parts even if that doesn't mean that the movie will surprise you much. But it is not about the predictability, but the fun you can have ... and you can have a lot of fun, if you let your guard down and just suspend your disbelief.
