That is one seriously cute kitty!
Re: Beryl, go for it, I reckon her thighs might develop adequately in time... then tell the family who Beryl is, in about a year's time.
Actually our animals rarely get addressed by their names. Tirion is frequently referred to as stripey ('cos she is) grumpy ('cos she is) or stumpy ('cos she walks all stumpy, like, due to a spine problem).
Baggins is either "big cat", "lumpy" ('cos he is, and it sort of goes with "stumpy") or "bloodyhellcatyourpawsareheavy" or sometimes, whilst I'm in bed "getoffmybollocksyoubastard". This said, I do love him dearly, and must get off my arse and post pics of the great lump here.
Surya is frequently referred to as "dog" (way too obvious to explain), stinky (ditto) or "getoutofthebloodywayyoustupidanimal" due to her tendency to be very friendly, to the extent that wherever you are trying to go, there is a border collie right in front of you. She is rightly terrified of the cats...
