Hello Joanne, Here is the LAPS website address http://cavies-laps.blogspot.com/ You can join if one of your piggies weighs 3lb. or over. This is not an excuse to over feed your piggies! Just a bit of fun. Penny and the well-fed Piggyfriends, who have 5 members amongst them, Daisy, Gulliver, Bramley, Rye and Barley and several in training.
