Buck Grease or Blood?

[Spaz1987]

I had just got home from work and noticed Gregory had these marks on him that weren't there before. So I picked him up and my first instinct was that his brother Nicky had bit him. But I looked through the whole cage for blood and found none. Then I remembered buck grease. Is that what this is?

Did you part his fur to see if he was cut in that area? That doesn't look like buck grease.

I did check for a wound and found none.

I wonder if someone peed on him …...

 

[Fidget]

Yeah, it looks more like he was peed-upon Hard to tell color, if it's really red maybe a little porphrin got on him and somebody's pee watered it down? Maybe keep an eye on his cagemates in case someone has a UTI?
Buck grease isn't wet. It's dry & orange-ish and coats the skin, tho it can flake and get in the hair but would be dry..
