Two years ago a got a rat from a pet store, who gave birth the next day to 12 babies.
We kept the mom and three babies.
There were a lot of pure tan ones and we couldnt tell who was who so they weren't named. The black capped one was jokeingly named 'Denty Head' because she had a slight dent in her skull that didnt cause any health problems. I dont remember what her actual name was.
The black one in the back was named Bean.
We got help from an cat rescue, hilariously, to get them adopted.
