Spiney
The only girl in the litter. She has a string of spots down her back, looking like a spine.
Spiney was very active the day I took these pictures. These were the only ones where she was still enough to get a non-blurry photo.
Bear
One of the three boys. The three spots on the lower part of his back looked like a Teddy Bear when he was first born. The similarity to a Teddy Bear is disappearing, but we still call him "Bear".
Snowball
Another of the three boys. The three spots, in decreasing size, on his lower back, looks like a snowman. As he ages, the spots no longer look like a snowman, and we started calling him "Snowball" because that is a better name than "Snowman".
Spots
The last of the three boys. The many spots on his back did not resemble any object (like a Teddy Bear or a Snowman), so we just settled on the name "Spots".
