Bobtail and regular tail kittens in Kingston, Nova Scotia

I have a male bobtail kitten , which is going for that reason we were told it was female , not the case. He is a dark grey tiger striped cat. Extremely playful and full of energy
I also have his sister which is a white/orange/grey striped calico cat we would love to keep her but our son has gotten sick shortly after we picked up the cats and I want to eliminate this from the list of possibilities she is super playful and loving
They come with a bucket of food , 20 kg left in a box of litter, a litter box and mat, 3 food dishes and a mat for under them also both have collars that don't yet fit them .
I am not 100 percent on their age but they are atleast 9- 10 weeks old
May beable to deliver.
