Tatty, the rabbit, is a weird case. Although he seems to be aged 8, something in his brain turned off long ago and he does not exhibit much of the behaviors one would expect from someone of his age. In fact, he is obsessed with his own penis, like a toddler would be. When we captured him and put him in the nursery cell, we kept him in the same clothes, including the broken handcuffs he was found with (apparently, his previous master was aware of Tatty's compulsive masturbation and tried to deter it), because he is toilet trained, so there's no need to put him in diapers. Tatty is fed regularly and kept under observation, like all other captured animals in the area, one quirkier than the other.
	Tatty is the most sexual of the twenty seven captured animals. While the others seem scarred, traumatized, Tatty seems to be happy with what he saw down there. That, or his memory repressed the horror of the underground. Either way, he will attend to some psychoanalysis sessions. He retains the ability to speak, but sometimes, when he is craving masturbation, his speech is incoherent. It is difficult to drill through his grunts and whimpers when he is such a state.
	We tried to measure Tatty's IQ and, although he exhibits signs of sharp intelligence, they vary in an inverse proportion to his arousal. When he is too aroused, he can't match shapes with their corresponding holes in a toy. Instead, he penetrates the holes with his penis, which also seem underdeveloped for someone his age. His sexuality is completely childish and he refuses intercourse with other captured animals, shying away from them, preferring to touch himself in blissful isolation or use substitutes for partners, such plush dolls. He has not responded to medication to reduce his sexual desire and continues to hump any toy he can get his paws on.
	We tried to test his tolerance to stress through regular means, by submitting him to overstimulation. We found out he responds poorly to noise and excessive light, but we decided to test something else. We attached two electrodes to his genitals and kept stimulating him sexually using electroshocks. He had several orgasms, all dry, but seemed to have an unusually short refractory period, allowing him to have multiple orgasms. We concluded that he could not be overstimulated sexually. So we decided to use another type of personalized stressor: a chastity device. He reacted aggressively to it, as if he had been submitted to it before. He could not put into words why he opposed to the idea so much, but we presume he can not admit his inability to abstain from masturbation. He had to be held by two nurses, while we tried to put the cage, but the scuffle caused him an erection. We attached the electrodes again and gave him orgasms to exhaustion. When he was unable to stand anymore, not due to overstimulation, but due to fatigue, he could no longer sustain an erection and the cage was put.
	We left the cage on for a full day and he was absolutely miserable, crying and pawing at the chastity device, trying to rut against plush toys, with no success. In such state, he began to experience fever. We took his rectal temperature and his erection, inside the device, became too painful and he wailed, having to be held again by the nurses. The fever was caused due to a virus he acquired during his days in the underground and unrelated to his mental state. By the end of the day, he was curled in a ball, trembling and unable to eat or drink. He even refused at first to have his chastity device removed, showing great distrust. But, as soon as the device was removed, he rushed to the crib he sleeps in and rutted against it, having multiple orgasms against the mattress, which had to be replaced in the following day due to becoming drenched in his musk.
	When he was calmer, he agreed to cooperate and we ran some tests on him in the next morning. He walked on a trendmill while elecrodes measured the course of the electrical signals in his body. It did not take long for him to start pawing himself while walking on the trendmill. We constantly had to remind him of our cooperation agreement and he struggled to not touch himself. At some point, the experiment had to be paused, becuase he could not concentrate. He was squirming, instead of walking, his hand-paws clenched into fists as he fought to not touch his half-erection. He was fed with a baby bottle and a sedative. He was allowed an orgasm and then he continued the experiment. After that, he was put in an ECG chamber and, during slumber, we ran a CAT scan and a MRI on him. The evils of the underground seemed to affected him moderately, but he could be reintegrated in society, if only we could curb his self-stimulation habit.
	He is currently trying to commit to having only ten orgasms per day. Next month, we will reduce it to nine and so on, until we can, hopefully, have him feeling satisfied with only three. The evils of the underground wear off with age regression, so he will be encouraged to act like a toddler and he was assigned a caregiver to treat him as such. We diagnosed him with autism and his IQ was finally measured at 134. He is kept in a padded room. He has a form-to-hole match toy, a crib and, sometimes, he is allowed to walk around the facilities and interact with other animals. He seems to be very fond of Severo, the cat rescued from the clandestine drug lab, but Severo is still hopelessly stuck, his progress in the treatment stunted. At least, they seem to understand each other.
	Tatty is taking food additives, risperidone (25mg, once a day) and is attending to both psychoanalysis and CBT. We expect to rehabilitate him in 18 months.
