I have a 4 year old female and a 3 year old male Dumerils. The female is eating large-Xlarge rats every 2 weeks is about 5-5 1/2 feet long. The male is eating medium rats every 2 weeks and is about 4 feet long.

Here they are, but the pic was taken last year. The other female I used to have is in the pic too, so it's 1.2 shot:
