I have been looking at this site for the past 6 weeks getting inspiration on how to build my own cage and figured"what the heck, I might as well join Im on here so much." I currently have 2 awesome male piggies. Max is our first who is about 6 months old. Our other, Thumper, is about 4 months old. They both have had URI's too. The little one has one right now and we just purshace him from petco on 12/30/08! Other then having to give them medicine everyday(such a pain ahah) they are great to be around. My 5 year old son just loves them!
