Can you catch toxoplasmosis from mouse feces?

Yes, as mice are warm blooded and can come into contact with parasites.

Toxoplasmosis can be transmitted by warmblooded animals, including humans, but the primary host is cats. Animals are infected by eating infected meat, by ingestion of feces of a cat that has itself recently been infected, or by transmission from mother to fetus.

Cats are often blamed for spreading toxoplasmosis, contact with raw meat is a more significant source of human infections in many countries, and fecal contamination of hands is a greater risk factor.
