Delta





Delta was a cinnamon patched.

Delta came to me with George after their owner had been told by her landlord that she was no longer allowed her rats anymore.
I was told that Delta was a hermaphrodite, and when I went to pick her up, it was obvious there was something odd about her.
She had nipples, like a female, but no vagina, and what appeared to be testicals. Her previous owner had been referring to her as a male and a vet had apparently told her the rat was more male than female.

However, to me, she had far more female features. She was the typical female size, had the softer coat of a girl, and had a more feminine face. In fact, the only thing that even hinted at her being male was the testical-like growths she had.
Below, you can see a pic of her underside, showing nipples and the swelling under her tail:



She also came into season like a female, and the male rats all reacted to her as if she were female. I was told she may be a female with an 'imperforate vagina', and from the pics I found of this condition in mice, it seemed to fit her far more than true 'hermaphroditism'. Hermaphrodite rats do exist, but they are very rare.
Delta was actually a very useful rat to have around. As she had no vagina, she could not become pregnant, meaning she could live with both boys and girls. This came in extremely handy when Tyrus lost his long term cage mate, Agent Orange. He was a rat who did not readily tolerate other male companions, but was too old to have castrated. Delta turned out to be the perfect companion for him, and he took to her instantly. They lived happily together as a pair for a long time.

Delta was a sweet, gentle girl and was pretty relaxed about most things.

As she aged, the odd swelling she had down below began to cause some issues. It began to swell up, and seemed very tight and firm. My vet saw her, and while he had never dealt with anything like her before, he thought the problem was likely to require some surgical intervention. What we were concerned about was that the swelling may become large enough to block her urethra or anus, which would leave us with big problems.
My vet said he had no idea what he was dealing with when it came to Delta, and that he didn't know what to expect if and when he tried to remove the lump. It was a very risky operation, with no guarantee of working, and my vet was in two minds about whether it should even be attempted. The estimate for the operation was almost 400.
Fortunately for all concerned, Delta's issues began to resolve themselves, and she had no problems long term with her strange anatomy.

She died simply of old age.

Why Delta? I named her after the movie 'Delta of Venus'.
