I’ve been seeing a lot of Abyssinian guinea pigs up for adoption recently. You can try searching for them on Facebook groups such as “PHILIPPINES ORGANIZATION OF GUINEA PIG” or “Free Pet Adoption Philippines”. You can also find Abyssinian guinea pigs from breeders; choose your breeder carefully and, if you would like, ask if you can meet all the piggies and the parents so you can find your perfect match. Hope that helped!
It is recommended that you feed your guinea pigs timothy hay, and that you give unlimited amounts of it. You can get timothy hay from Cartimar or Tiendesitas, they sell large bags for P250 each. But if you would like to shop online, I recommend getting your supplies from Pet Supply Depot. They sell Oxbow and Kaytee Timothy Hay there too.
