Thank you for your inputactually the two known males were adopted out to amazing homes and I am getting regular email updates and well visits when they are in the area as for the two in the pics the top is a proven female...the other probed male but idk my last probed female turned out to be a big boy...not to mention the two in these pics came from the same location the girl had them for 3 years from when she worked at a petsmart or petco and she saved them....though not sure when the scar was caused on the bottom one they are both on f/t med rats
