Every year, SVA examines thousands of animals - both domestic and wild.
In this year's Christmas calendar, the third in a row, SVA's pathologists show pictures from autopsies of animals.
Behind the doors on Instagram, for example, is a cat brain and a dead-bitten bat.
- The calendar moves on the border between disgusting and interesting and the interest is great - many want to know what happens to the animals.
We can help explain why they die, says Karin Olofsson-Sannö, assistant state veterinarian at SVA.
Have you got more followers on Instagram now?
- Yes, it is constantly increasing from year to year.
Most are people with an interest in animals - hunters and pet owners.
And so a lot of veterinary students.
"Show more"
So no one gets disgusted?
- No, on the contrary - many comment that they want us to show more.
Which gap should the most sensitive skip?
- I do not remember the number, but we have a wild boar lung in the picture where a small grain from some grain has crept down and caused a pneumonia, says Karin Olofsson-Sannö.
