Wren asked, in yesterday's comments, if Scruffy could be pregnant.
I don't think so; it's a bit early. These squirrels normally breed in March or April.
But you be the judge:
1. Here's Scruffy, this week. Notice how uniformly rounded she is. She still has the scar on the upper back, which shows as an indentation in this photo; it's hairless.
2. Here's Scruffy, last January 14th, almost a year ago. (Aside: compare the background; snow vs. green grass.)
She has a distinct "waist" in the older photo. It's gone, now. And now her body dwarfs her thighs.
3. Here's Scruffy, probably pregnant, the 12th of March, last year. (Counting back from the date the kits were weaned. 36 to 40 days gestation, 6 to 9 weeks of nursing.)
She still has a bit of a waist.
4. And here's Scruffy, no longer pregnant, June 4th of last year. The kits turned up for snacks a week later, so they must have been at least 5 weeks old when this photo was taken.
So: what do you think? Pregnant, or just well-fed?
