Best place to get Pinkies and feeding ?

I have been getting my Pinkies at PetSmart and they seem a little small. I was wondering if there was somewhere you could get different sized Pinkies. I think Fuzzies are too big right now (I've had my snake for 1 month and he was small when I got him). However, he eats immediately without any issue and I think he wants more. I just didn't know if it would be best to offer him 2 medium pinkies at once or keep him on his current diet of 1 medium pinkie every 5 days?

Also, is there an age guage anywhere so I can estimate how old he is?

the best source would be a local feeder breeder or a reptile show where feeder vreeders sell miec and rats. Petsmart is a bit expensive. Here they go for almost $2 each ay Petsmart. At the local reptile show they are about $.30 and they come in every possible size.

You could order online but for just one snake you'd end up with far too many pinkies, and shipping can get expensive.

Another option would be a pet shop that specializes in reptiles.

Google local pet stores

I would google pet stores in your area and see if there are any like "off brand" stores. Not petco, not petsmart. Maybe try a "creatures and critters" or just mom and pop stop. Alot of them carry feeders of all sizes (frozen and live). I would just call around to any you find in your google search and see what they offer. If not worst case scenario you could go to the "feeders" forum and get more advice. Alot of people in there can give you above average advice on starting your own mouse colonies. But I haven't done that as I only have one corn and don't need that many. Good luck in the stuff you try. Last place I'd say to look is some of the banner ads you see on the site, lots of reptile sites sell under costs you'd find in a pet store and will ship fairly quickly. Don't know if your willing to do that for feeders, but just another option. Good luck.
