was going to get a tank when i was in Michigan for family stuff but low and behold if you aint a petco club member the tanks cost more if rember right could of joined and saved 5 bucks on a 10 gallon tank but cost of membership made it to where i would of paid more.

really funny part was petco in MI don't know how to sex mice i had to give them the run down on how to sex them. got 10 supposedly female mice got back to where i was staying at and low and behold balls everywhere all but 1 was male and they took them out of the tank that said females so called the store up and asked what happened they said bring them back and they would swap them out so 45 minutes of sorting mice they finally came up with 10 females guy thanked me for teaching them how to sex the mice they were going by spacing of something i told them just go by if you see nipples from front to back its female (I've yet to see a male that had 10 nipples) got all the way home mice are in quarantine cage and still no balls showing (well other then 2 mice that look like wild mice but i picked those just for that reason to add some new vigor to my mice)

needless to say the store manager wasn't happy with the person they were getting there mice from as they had a 20 gallon long of what was suppose to be females and got only 10 females out of a cage full there was at least 50 to 60 mice in it. before i left he asked if he could use one of my females i bought to show what to look for from now on when people ask for female mice

but it was really clear even the store manager didn't know what to look for as he opened my box of mainly males and asked what the problem was and all their balls were hanging and the receipt he was looking at said females
