If you do not weigh weekly, set a weekly calendar reminder. The data compounds; missing entries do not.
Weight loss — when it is normal vs when it warrants a vet call.
Adult panthers fluctuate within a 10% range across the year. Sustained loss of more than 10% over four weeks is a vet conversation.

Weight in adult panthers naturally fluctuates with seasons, breeding cycles, shed cycles, and individual personality. A male holding within ±10% of his stable adult weight across a year is normal. Concern enters when: weight drops more than 10% over a four-week window, drops occur alongside reduced activity or appetite, or the loss is concurrent with visible body-condition changes (visible spine, sunken hip area).
Bring the weight log to the vet appointment. Numbers tell the story faster than narrative description, and the vet will use the trend line to decide what tests to run.
