Therapy animals are amazing.
There's a care home near Birmingham that has two goats, one pig, two rabbits, a guinea pig, ducks, chickens and an aviary of birds as part of a three year study into the effects of animal-assisted therapy as a form of intervention for people with dementia also suffering from depression or anxiety. Apparently the residents keep sneaking treats to them!
Oh, that's so awesome! I want to pet therapy goats right now.
