Merlin never really liked dogs that much, and couldn't seem to find the right one while searching for his "companion" after being discharged.
In comes Harry: a pretty little kitten that Merlin immediately falls in love with. They make a little family of just the two of them, until Harry brings home an unexpected guest: Eggsy. Eggsy is equally as pretty as Harry was, aside from a few minor cuts and scrapes from living on the streets.
Together the three of them live and grow as a family, with unconditional love for everyone (well except Arthur. Fuck Arthur)
