Hello all you shiny happy people. How're you and your little lovies? Doing well, I hope.

The ones here.. Not quite so well. Or, well, maybe not. Not entirely positive, and honestly? A bit worried.

There are a total of four balls present in the house I'm living in--Two males, two females, if it matters at all. One male about two years of age, the other roughly a year. One female almost three years, the other about a year as well.

For the past month, we've been encountering some issues regarding the two older snakes--Namely in feeding. Somewhere roughly about the same time, the two eldest decided that they really didn't feel like eating anymore. Initially, this wasn't a tremendous concern, but as time has gone on, we're admittedly kind of worried about their health and whether or not something is actually wrong with them.

Of course, we figured the forums here might be the best bet to try and figure out what may be the problem--If one is there at all.

Some background:

The snakes are being fed thawed mice. This -likely- isn't much of an issue, as they've been eating thawed mice for years, now--And moreover, the other two snakes are devouring them just fine. We haven't changed suppliers, either, since starting them on thawed mice. There's been attempts to try and heat the mice and jiggle them around to make them more tantalizing a target, but this hasn't really had any sort of effect.

Temperature and humidity are well within the ranges they should be, and consistent between all four ball pythons. Again, we doubt this is really the core of the issue.. But, well, information helps.

There's been consideration that maybe it was due to winter being around, but now that we're entering into some very fine weather patterns, that seems out of the question. Moreover, the weather hasn't really affected the two younger snakes' eating habits, either.

There's been no real change to their surroundings, either. It was thought that maybe this all was due to some kind of proximity between the two of them being around breeding age that could be causing a problem, so the female -has- been relocated to another room on a different floor of the house.. But this hasn't really resolved the issue, either, for either snake.

Also, again.. This started at roughly the same time for both of the snakes in question.

There's a decent degree of worry if there might actually be something wrong with the two of them, considering it's been somewhere around a month and a half for the male, and a month for the female. Any advice, suggestions, or.. Well, anything.. It'd be appreciated.

Thanks!
