So I have a 4 1/2 yr old female Silver Martin. Generally very healthy overall. Recently (for the past 4 days) I've noticed her lying down more frequently (day/night/morning) and in random spots. She typically has her comfy spots she lays down on when she's relaxing, but now it can be in the middle of the kitchen which she never does. I'm looking closely for any signs of pain or discomfort. Can't seem to find anything like that though. Her appetite seems fine. She's a picky eater when it comes to hay but she'll eat a good amount throughout the day and night. Treats are limited for her but she's fine with them as well. She is in a healthy weight and her posture while lying down is more relaxed then hunched over (as if she would do while in pain/discomfort). Can't seem to figure this out. When i get her treat out, she'll run to me fast like she always does and she'll sometimes be the she's always been and act out.

*Important side notes - She's taken a small tumble coincidentally the day before this all started. Nothing severe, her usual tumble when she panic jumps off someones arms. Also, its been humid the passed few days as well. Wondering if the humidly could have her in this low energy phase, as I read it can.

Nothing else seems off aside from her lying down much more often. As if she's low energy in those times. Any thoughts or suggestions would be great. I already plan on taking her in tomorrow.
