welcome to the forum! what different names they have XD what's the story behind it?
first timer tips are to check the gender, then let piggies settle in a for a full day or more, resist alll temptation to pick them up for cuddling!
have hay,pellets and water in the cage at all times, avoid getting a pet store cage if possible. depending on their previous owners/pet stores, they may not be used to vegetables so you might want to start slow and focus on lettuce and bell peppers first. lettuce is a staple, bell peppers is a good source of vitamin C
if they eat it , all is good. leave it in the cage, they might be too scared to be handfed for awhile. you can try though after a day or two.
if they don't eat it, slice it into very small pieces and mix it with the pellets so they get used to the taste
do share your cage plans, bedding plans or diet plans if you'd like more tips from others
