Just a note - pothos is high is oxalic acid (like spinach) which binds with calcium and prevents it from being metabolized. It forms calcium oxalate - a salt that accumulates in the kidneys.
My veileds have never eaten the pothos - but if yours like to munch on them (or the fiscus) the schefflera (umbrella plant) or hibiscus (forgot that one!). I really like hibiscus for little chams - it has lots of grooves on the leaves which hold water droplets well.
The hibiscus probaby won't be sturdy enough for an adult veiled - unless you can find one in tree form. You can get the schefflera for about $10 (3-4 feet) at Home Depot or Walmart.
