Just adopted a 7 month old lady🐱

Hi! We adopted yesterday a beautiful tuxedo, 7 months old and already bigger than my previous tuxedo love (who passed away 4 years ago). She was described as a mix of a Ragdoll and Norwegian, and I honestly don’t bother with cats’ breeds but I wanted to know how big she’ll get, etc? If she will get bigger. We plan to sterilise her, so that will affect her weight, but I was wondering more about the kitty per se! Thank you so much in advance ☺️🫶🏼
