they can see pretty good. honestly if its drinking & doesnt seem interested in food today, maybe just give as much privacy as possible & try again tomorrow. when i i got my adult male panther, i was getting scared cuz he wasnt intersted in food for a while. i just let him do his thing & as soon as he snagged the first one he became a serious pig within seconds. id even consider covering the enclosure with a sheet for a day. if it takes any more than another day or 2, id seek advice froma more experienced keeper on here. theres a lot of great advice & keeper floating around on this forum. just keep reading even if your not in the mood to post.
