Links of places I've used personally & highly recommend.
As I won't preserve Pets, I direct those who ask me to contact The Pet Cemetery in Holywell.
Having cremated 2 of my beloved animal companions so far (the latest being my elderly cat on the 25th of May 2018.) I can wholeheartedly recommend the service they provide.
The well maintained grounds containing 100's of beautiful animal memorials, where you can sit and watch the ducks swim on their own pond or have something to eat in The Pet Cemetery Tearoom, where dogs are not only welcome they actually have "their own menu" of goodies to choose from (My Maisy likes the the sausage & bacon!)
