got some pretty expensive things posted so far! I think the most Ive spent on one item would probably be either the crate or the cat tree (plus oversized shipping for both). I also bought a $50 collar for alki. lol then theres Brock's "medicine" (digestive enzymes) which costs about $140 (or more, I think it just went up) a bottle, each bottle lasting a month or so now I think. but my dad is paying for that right now thankfully.........
