It was earlier in July that Sanna Widell and Erick Johansson took Kattis on a two-week cycling and hiking holiday around Norrland, which ended in Nikkaluokta at the foot of Kebnekaise.

- Her needs went before our own. We were prepared to turn around if it did not feel okay, says Sanna Widell, Kattis' mother.
