Anyamal Tantei Kiruminzoo EP1 - We Kirumphosed!?

Riko Mikogami and Rimu Mikogami are asked to look after a cat called Laila who supposedly is not feeling well. Soon the cat runs away because the 'Doctor'(who is a turtle) almost landed on her. They find the secret stairwell leading to the attic and discover the 'Kirumin' devices. Riko and Rimu use these to transform for the first time. They chase the cat outside and both manage to use their animal form to get out of danger.
