Tempy is a big rat, at least 50% bigger then my other 3, just in overall size. But lately he's looking a bit fat. He's got some rolls on his neck and he look pudgy around the middle. I'm worried he might be getting obese. How do you get a rat to lose weight? We don't feed them much in the way of treats other then a couple times a week I give them some veggies. (Broccoli, kale, tomatoes, cauliflower, peas) Other then that we let them free range on Oxbow which they don't seem to go through that fast. (Fill their bowl maybe every 4-5 days) Maybe I'm just wrong? He doesn't feel squishy at all. In fact he feel like a solid muscle when you pick him up. But he looks chubby, especially around his neck and face.
