2 y/o male corn not eating

Hi everyone

Fluffy is 2 and a half now, and last month we upgraded him from big mice to small rats. He took the first rat just fine on 21st March (still amazed by how stretchy he was), but hasn’t eaten since.

I know it’s mating season, and that probably explains him not eating. Also explains why he seems to be out and about more than usual; looking for a lady rather than hunting. How long this is likely to go on?

Would buying another pack of mice just be a wasted effort/step backwards; is that probably just a coincidence of timing rather than him expressing a preference? Should I simply keep trying to feed him every week and trust that when he’s hungry enough he’ll eat?
