No idea lol, didn't feel the need to have her scanned as it was obvious she's in whelp. She'll get bigger too she's still got to drop down.
I'm guessing 9, she was one of 12 and Stan was one 9.
Her sister Pea is due any day now and isn't as big so we think she's probably got 6 or 7, she had 5 last time, which is actually quite a small litter for a Viz.
