Fat deposits 2 ways - sub Q and intramuscular. The latter is not readily detectable by feel. Large muscles and fat both can limit joint mobility/flexibility. Large muscle mass requires resistance exercise to develop. Most ferrets get endurance type exercise which causes toned lean muscle mass (e.g., a runner). If your ferret looks fat, lacks flexibility, and is not pumping iron, I'd bet intramuscular fat is a distinct possibility. We have two very strong male ferrets that weigh about the same but differ noticeably in size. One is lean and the other is less dense and must have intramuscular fat. (Muscle is denser than fat.) >I'm also paying attention to photoperiods based on Mo'Bob's recommendations >and theories.

As with the other postulated causes of adrenal disease, there is no evidence that photoperiod is at fault. I'm a research psychologist (not an actor playing one on TV) who has experience in photoperiod effects in humans. The light levels required to cause an effect are well above normal house ambient lighting. There is a threshold value that must be exceeded. If not, the lunar illumination cycle would play havoc with the durennial progression (jargon terms for Mo Bob's benefit - he says they're required for credibility). Nobody (including the estimable Mo Bob) has proposed a specific mechanism to explain a relationship in the lack of data. For example, by this I mean that the change in day length cases the pineal gland (usual master gland in this situation) to secrete hormone X which acts on gland Y to cause Z, etc. The only thing offered is a general description of seasonal effects and not why a usually unaffected gland suddenly becomes involved. The adrenal is not a primary sex gland and I see no clear mechanism to involve it in the light related seasonal sexual hormone level changes (for which there is a specific mechanism). Interestingly, Dr. Judi Bell (ex MF vet) has suggested an interaction between early neuter and photoperiod with a vague mechanism rationale of the detail level Mo Bob gave. The problem I see is that this *might* explain the ferrets sold (and therefore not observed by Dr. Bell), but not the whole ferrets in manipulated lighting that Dr. Bell did observe where she did not note a problem. (I could have said "see" but "observe" is more technical to add that subliminal credibility.) I can identify with your desire to avoid adrenal problems. Let's say your ferrets don't get adrenal disease and you avoid natural photoperiod disruption. What have you shown? In just shy of 10 years we've owned 13 ferrets and had only 1 with adrenal and all with unregulated photoperiod exposure. With this small sample, chance could explain the lack even if photoperiod is a cause. The same goes for the reverse conclusion. I don't believe that photoperiod is a cause, but have no evidence. I'm not aware of anybody that has buried a potato with the full moon shining over their left shoulder having adrenal problems either. This is how superstitions start and the reason for my warning. We have too much superstitious thinking on the FML already. (Try the potato anyway - it may work.) If you want to go to the hassle of controlling light, go ahead, but be careful about any effects you attribute beyond the proven sexual ones. You may be right, but you may be wrong too and still get the desired result. >Also, if an experienced fert-person in the SF Bay Area wants to meet Hairy >Crumb the body-builder and confirm what I'm seeing, I'd love it.

I wish I could see Harry and show you Springer and Smokey mentioned above. We could talk motorcycles too. However, given the legal situation, I don't know how wise it would be to take up a stranger on this offer. You can do what you like (you seem assertive). But the risk to your ferrets is much greater than from lamp light at night. The experience may be in seizing ferrets. This is the problem people have in risk assessment. You worry about adrenal disease and ignore seizure because of the difference in perceived situational control by you. Statistical risk is not intuitive or like daily experience. It's like the joke about the guy who always takes a bomb on a plane because the chance of 2 bombs on board is astronomical. Statisticians are just as funny as zoopalentologists.
