Mapleflight's litter

I'm not sure if the grandparents matter, but I'm going to put them in just in case.

The kitten heritage is...

Maternal Grandmother: A tortoiseshell she-cat with yellow eyes. She has medium-length, fluffy fur that makes her look a bit bigger then she really is. She's on the small size for a female cat, and has a heavy build. She's developing arthritis with age and she had difficulty carrying a litter to term before Mapleflight and Frostfang.
Maternal Grandfather: He's a short-furred white tom with blue eyes. He doesn't have any hearing problems, but his brother was born deaf and was killed by a fox shortly after becoming an apprentice. He is of average size for a tom, with a stocky build.
Mother: Mapleflight! A short furred calico she-cat with yellow eyes. She's healthy. Mapleflight has had no physical health problems, but it's possible her problems focusing on things stems from a genetic condition. Cat ADHD? She's small but has a very sturdy build, like a tiny meat brick.

Paternal Grandmother: A silver tabby she-cat with yellow eyes. She had long fur. She died from greencough, but had no notable health conditions in life other then the disease that killed her.
Paternal Grandfather: A black tom with green eyes. He has short fur. He is still alive, but has retired to the elders den early after the death of his mate. He has been frequently plagued with lung infections his entire life, probably a result of the amount of time he spends in the water.
Father: Silverwing. A long furred gray tabby tom with green eyes. He has had no notable genetic health problems. He has some problems related to becoming overheated because of his heavy coat. He's large but he has a thin, agile build underneath all that fluff.
