RIP

I sound really stupid right now but my head isn't working properly. I got two rats for my birthday last year. They are beatuiful. There is Densil who is white with a brown head and brown stripe down his back and Doughnut who is completely brown. I love them so much and they mean the world to me...... Until today. Im crying super hard so Im sorry if this doesnt come out too well. Recently Doughnut has been stealing a lot of food from Densils hands. So I had to feed them seperatley but Densil still wouldnt eat without Doughnut. And about twenty minutes ago I went to feed them and I found Densil in the food bowl. I opened the cage and he still didnt move. By then I knew he was dead. I started sobbing, put food out for Doughnut and my dad put Densil in a little box. But what is even worse is that rats live in pairs so it is extremely unlikely that Doughnut will survive on his own. So now I feel like it's all my fault even though its not. But I hate myself even more. I dont want to do anything. I just want to stay in bed and cry and cuddle Doughnut. Densil was fine this morning. I loved him so much and now..... RIP to the most gorgeous little ratty in the world...... Sorry baby. Mummy still loves you.... GoodBye.
