Cool!
You’ll definitely want to replace the cage flooring sooner rather than later, as they could chew right through that plastic drop cloth.
If you find they chew the coroplast edges, you can get plastic report covers (the sort with a folded sheet of clear plastic to protect the contents, and an opaque plastic “spine” that you slide over the clear bit once you’ve put the papers inside). We’ve got the edges of our current cage’s coroplast done up with those edge pieces. The piggies had chewed one corner of the coroplast (the corner nearest the rest of the house) down to the floor of the cage, requiring us to redo the coroplast bit.
They will, quite possibly, be afraid of you for some time. Of our first 3, one (Sherma) would come running for petting, the second one (Cinnamon) would tolerate it and purr, but wouldn’t approach me for it, and the third (Panda) would actively run away from my hand pretty much the entire time we had him. Sherma and Panda are now gone and have been replaced by Pig 4 (Ulysses) and Pig 5 (Vera). Of those: Cinnamon still tolerates petting and will purr. Ulysses runs like hell when I try to pet him, and if I want to pick him up, I have to corner him in the pigloo and grab him from in there. Vera sometimes bolts, sometimes tolerates petting.
All 3 of them, however, will settle down nicely once I do succeed in picking them up. The only one who never settled was Panda. There were several times when I was holding him where some sudden noise would startle him and he’d try to leap out of my lap / arms. Leading to one poor fellow who came to the door, being greeted by me opening the door, a black and white blur flying through the air and onto the floor, me shrieking in alarm and bolting away from the door in hot pursuit of the terrified guinea pig. I finally caught him and had to rush him to the vet… then tell the kids that I broke their guinea pig (the pig made a full recovery - fluid in his lungs and broke both teeth, but with appropriate meds he recovered and lived another 4 years). That tradesman never forgot that visit, I’m sure!
Oh - did anyone mention that they purr? Not all of mine (Vera has never purred, and Ulysses will only purr rarely, when I’m holding him and stroking him and he accidentally lets his guard down), but the others will, when stroked from behind the head along their body down toward their rump, make a sort of shuddery OOOO-oooo-oooooo-ooooooo sound. This’ll start happening once the pigs are more used to you and relaxed around you.
The shrieking for food is fun too. We’ve decided that they’ve got us trained to give 'em yummies whenever they wheek.
