Ive had my ball pyhton for around 3 weeks. it hasnt pooped yet. its tail is unusualy fat. should i be worried? I know balls can go 4-6 weeks without going but i thought it to be odd thats its tail seems bigger. it has eatin two mice both on the last two mondays. it seems to have a buldge from its spurs going up about 2 1/2 inches. is this normal? this is my first snake...
