Reggie won't eat.

He's 3.5 years old and has always eaten a live rat every other week. It's been 5-6 weeks now since he's eaten.

He normally eats in his aquarium home. I've tried to put him in a separate container with the rat but all he does is buddy up to the rat.

I've had to euthanize 3 rats now over the past 3 weeks.

Any suggestions?

Thanks! :)
