Aww Bloom is a cutie, reminds me of one of my first girls, charity. I think I saw pellets in a bowl. Not the best as you now know. For the mean time, try scattering some of the food about and then with the food bowl altogether and use of as a water bowl instead
I love black rats and red eyed rats. The ones that creep people out and I suppose the ones people don't like. I have a black self. I'll add a photo to show what rusting looks like. She's currently stuck in moult but is slowly getting through it. Also giving extra copper can help
