This has been covered before but it still shocks me. I breed all my own rodents and recently started selling my excess locally, until today I have never purchased a rat from a pet shop, I wanted to clear up just what weights are expected for adult, large, extra large etc as my customers are confused so I checked out Pet Barn and as research bought a packet of 3 "extra large" Dolittle Farm rats. The pack of 3 cost me $58.99 and weighed a total of 489gms including a fair bit of ice present, that's 163 gm per rat, probably less than 150 without the ice. I define all my rodents by weight and don't give them size names but my definition of a 163 gm rat is only sub-adult, adult are 200-240gm, large 250-280, extra large 300-350. How do Pet barn and their supplier Dolittle Farm (no Wokka they did not have yours) justify calling 150 - 163 gm rats extra large and the price of almost $20 a rat is ridiculous, I bought a large leg of lamb today (not from Pet Barn) for less than that. A 500gm 3 pack of my sub adult rats is only $15 total and my 300 - 350 gm are $7 each. 3 sub-adult $15 with no ice. What started as a way to sell some excess rodents is now becoming a crusade, I can easily expand my rodent production and I am looking at low cost distribution methods, I don't care about profits as long as I can cover costs and feed my snakes for free. A lot of people with one or two snakes are reluctant to expand their collections as it can cost $100 a month to feed 3 pythons and what about the price of small mice. Mice breed like crickets or flies and should not be $3 each for fuzzies and hoppers.
