I've noticed my car has been leaking quite a lot of oil lately so I took off the underpanel to take a look. Why would oil be all over the passenger side cat? I'm thinking it's just from the oil in the belly pan blowing on to it (?)

I can't find any leaks after degreasing everything, so I guess I'm going to have to dig deeper.... any ideas?

Valve cover gaskets? Oil pan gasket?

...a lot of the gaskets (valley pan, valve cover, cam shaft seal, intake), and re-torqued the head bolts. Oil was dripping down the back of the engine, then at highway speed was blowing back over the tranny onto the cats.

it will probably be near the oil pan under passenger. If it is then its a pain to fix. You could try those oil sealers?

what kind of converter is your driver side one?

but in addition to that there is probably a motor oil leak elsewhere.

...best option would be to replace all gaskets (head/valve cover/valley pan/both oil pan/intake/etc...).

Yup, those hoses like to get brittle over time.
