How big will my kitten get?

[KittenTax]

We know he will be big but wondering if anyone can suggest how big. He is 4 months old (well will be tomorrow) and weighs 3.3kg! (This was from me standing on scales without him and holding him so not the best measurement). He is also a fluff ball which makes him look bigger.

His brother is not as big and comes in at 2.7kg

Here is my small 3kg fluffy cat as a trade

Some photos as requested. They are a wonderful pair. The grey floof demands to be brushed everyday and the grey and white is a chilled out dude.

Gorgeous! You can really see the giant size.

@KittenTax That is a load of furry loveliness

what luscious fluffy kitties.
thanks all for posting!
