dont worry... i got an adult albino nelson, 2 years 4 mths old, been keeping her since a baby. at this time of the year.. nov-dec. she tends to not eat. maybe mating season, but i dont want to breed her. she's just a pet.
when i offer her food, she eat p/k mice. she'll just play around with it. pushing it here & there.. dont worry. as fergie say, if it start losing weight.. then worry.
some time too much trying is no good. trying skipping a week or two. then try again.. Happy New Year!!!
