Hmmm opinions needed?
Ria and Roo were caught Sunday afternoon, and I got them Monday night but didn't weigh until Tuesday morning, so last exposure to possible male wild rats was Sunday May 10th, AM.
Ria (mom) intake weight was 266 g, she weights 262 grams this morning so she's lost 4 grams...I can rule her out as pregnant at 13 days.
Roo came in at 200 grams, and after a lot of ups and downs she weighs 223 grams today, a total of 23 grams in 13 days, but this could be food/growth rather than pregnancy weight.
No steady solid gains that creep up daily, so what's your feeling?
