Well rats aren't my favorite animals in the world, or else I wouldn't be able to feed them to the snakes, but I do enjoy my breeder rat colony for the most part. Until today the only losses I have had were females in labor and one old breeder female. A couple days ago while cleaning I noticed my oldest breeder male, a very nice Siamese, seemed to have lost a bit of weight. He didn't look horrible but he felt lighter when I picked him up. He started getting a little "rough around the edges" some months ago. When I noticed his weight loss, I had a feeling that his time was coming to an end, so I put one of his sons in his tub to hold back, which I think is a Himalayan. Tonight when I checked on everybody I noticed that the old male had passed away. It was a bit saddening because he was a very nice rat, I had him for a good while. RIP and many thanks.
