Doodlebug was a rescue I took in a short while ago from a run of the mill 'haven't got time for him anymore' situation. The previous owner said that her vet had said Doodlebug had downs syndrome :/ Now, while this condition has not, to my knowledge, been diagnosed in rats yet, it has been discovered in cats, monkeys, and non-human apes. So while I don't necessarily think he has downs syndrome in exactly the same way we would see it in people, I am open to the idea that he has a similar condition, or a rat version of it. He shows most of the physical traits associated with this condition in humans. But regardless of what it is, there is definately something not right about him, as you'll see from his pics. For his personality, he is generally timid and squeaky. Despite having lived alone his whole life before I got him, he has settled in well in my 'special needs' group, and is definately more a rat rat than a people rat. He doesn't like being lifted or held, but he is happy to lay on your lap and chill out. He likes licking, but only when you rub his ears. He does tend to have tantrums when things don't go his way, in a manner I've not seen before in over 14 years of rat owning! But he's generally a sweet, if rather....'immature' boy. I have yet to come across anything like this in a rat, and don't know what causes him to look the way he does. Im not sure if its an actual named disorder that I just don't know about, or whether its a combination of several individual problems, or whether it was caused by some kind of vitamin deficiency in his mother, or whether it is in actuality a rat version of down's syndrome. Hydrocephalus crossed my mind when I first saw him, due to the pointy upturned short nose which tends to occur in these rats, but he actually has no forehead swelling or any neurological problems. His head is pretty flat (though some of the photos can be misleading regarding that, trust me, it is). But he's gorgeous, and I love him to death: http://www.shadowrat.com/rats/doodle1.jpg Unfortunately, due to his shortened face, he suffers the same problems as dog breeds with shortened faces, which is snuffling and weepy eyes. The vet has said not much can be done about this and its a structural problem with his skull. http://www.shadowrat.com/rats/doodle2.jpg http://www.shadowrat.com/rats/doodle3.jpg http://www.shadowrat.com/rats/doodle4.jpg http://www.shadowrat.com/rats/doodle5.jpg Though it may not be apparent in photos, he also has a shortened body. Its very easy to tell once you get hands on with him. As well as this, he has a shorter tail than a normal rat, and little muscle. He's very 'bean-bag' like to pick up. He is chubby, always has been, but he doesn't eat excessively. He doesn't eat as much as I would expect a rat of his size to eat. http://www.shadowrat.com/rats/doodle6.jpg http://www.shadowrat.com/rats/doodle7.jpg http://www.shadowrat.com/rats/doodle8.jpg Its not just in the photo; his eyes are actually wonky too, one is at a different angle to the other, and there is no symmetry to him! https://www.facebook.com/media/set/?set=a.10150578845088064.441028.628043063&type=1&l=cce3695f15 https://www.facebook.com/media/set/?set=a.10150425682873064.417196.628043063&type=1&l=c310481fa9 https://www.facebook.com/media/set/?set=a.10150423898028064.416855.628043063&type=1&l=611f5fc418 Thought people may like to see his pics. I love him immensely, but would like one day to see another like him, or get some idea of what actually causes his odd features. Fortunately, despite everything, he seems mostly unaffected by any of it, and leads a pretty normal rat life.
