@markojen13 and @astrea Hi, Filipino here too. Welcome to this site! You could also join this Filipino GP lovers group on Facebook. The group, however, is pro-breeding, which this site strongly opposes. So advice lang: This forum and the Guinea Lynx site is still the most reliable site there is about GPs. Mas marami kayong matututunan na TAMANG pag-aalaga ng piggies dito.
Be careful with the grass. Bawal ang cogon grass or kung ano-anong damo lang, kasi makati yung ibang grass. Best you can find in our country is wheat grass. Bermuda grass is a bit okay too.
Btw, if you need a vet that specializes in GPs, (broken link removed) is the vet to trust. Doc Nielsen Donato of "Born to be Wild" TV show on Ch. 7 works there and specializes in exotic animals.
