Hi everyone, today I found a massive amount of blood everywhere in my chinchillas' cage. (By a massive amount, I mean on their wood ledges, fleece blankets, hammocks, etc.) I have done a general check on both of my chinchillas' bodies and saw no sign of injury nor can I spot any dry blood on their fur. Both of them are acting normally and are active like usual. I have had these two for five years now and this is the first time I've seen this. Both are female and they've been living together during the five years I've had them. I'm really worried and I have no clue what's wrong.
