Are they really that rare or is there an issue with them again? I'm thinking about getting the spray and cage. Is it really worth it?

Its worth it, but it can take awhile for it to kick in. I seem to average one every week or two.

Really? Wow, seems kind of scarce to get ahold of.

Thanks though Rain!

It's worth it, as long as you remember to keep both in your inventory. I missed out on a 45M item this morning because I had my spray put away for the "Capture a Lizard" achievement. xP

But really, after one or two events, you'll most likely re-earn the sP you spent both the spray and the trap, if not more.

i earned my sp back for both items with the first lizard event that i got. right now i have my spray put away for the ach but it's definitely worth it.
