My french lops,sugar and spice

Here are some pics of my babies,they are house rabbits and have their own bedroom but come downstairs from tea time till we go to bed. They have got their own personalities already with sugar been the brave one who jumps on the couch etc.They are now 18 weeks old but they only weigh 4 1/2lbs and 5lbs although the gap is closing between the two of them,are they likely to still get big ?

Hiya,frenchies aren't fully grown until 18months.My french lop,B,is 3years old but is a small frenchie,weighing only 9lbs.My last french lop weighed 15lbs most of her adult life.They are such a lovely breed of rabbit & your 2 are stunning!

Thankyou,they are in my bad books today cos they just weed on my new rug lol
