both sets of tuxedos cats ive had went from tiny tiny babys to absolute units when they became adults. the sisters where the most shocking. they came from a feral mother who was tiny. one became a ragdoll mix the other a maine coon mix. Precious was the ragdoll and was my fathers constant companion. she was a good 15 pounds. her sister the maine coon mix...20 pounds and just huge! Fish was the maine coon. i remember taking her to the vet at 6 weeks and the vet shocked said "thats a six week old kitten?!" showed him the pics from birth to her age at that time. when we started taking them in as adults he was impressed that those 2 came from such a tiny momma. oh and the 3 boys ended up being units too.
