Verify your light timer's actual on-off times against your phone clock today. Drift over fifteen minutes warrants a new timer.
The seasonal photoperiod question.
Wild panthers experience a 11–13 hour photoperiod swing across the year. Whether captive panthers need that swing is a question worth a real answer.
We run our males on a 12-hour photoperiod year-round and our breeding females on a soft seasonal swing — 11 hours in winter, 13 in summer — to mimic the cues that synchronize ovulation. Outside of breeding context, the year-round 12-hour schedule produces healthier outcomes than a guess at seasonality.
The bigger photoperiod question is consistency. A timer that drifts by an hour every season because of a power blip resets the animal's circadian baseline weekly. A reliable timer with a battery backup is a small investment that pays out over years.

Tightening screen tension on a year-old cage.
After twelve months of misting cycles and live plant weight, screen panels sag in ways that quietly compromise climbing surfaces.
Building a Ferguson Zone 3 UVI gradient.
Panthers want a UVI gradient running from roughly 0 in the deep canopy to 4 at the basking spot. The fixture choice and mounting matter more than the bulb brand.
Why we weigh every juvenile every Wednesday.
Grams do not lie. A juvenile that is gaining is a juvenile that is about to colour up. A flat week is the earliest signal you will get.
