I found mine to be extremely tight, to the point that I too was worried about ripping off the foam screens built into the mics. I thought at the time that my set was an anomaly of tight fitting. Instead of ripping off the foam, what happened is one of the rats broke at its "mouth" while I was trying to stretch it a bit to put it on one of the mics without tearing the foam. I thought this was a defective one, and Chris replaced both rats for about half the price of new. When I (finally) got them back, the replacements were identical in fit so clearly this is by design. By that time I had sold my CA-14s, so I used them on my other mics and ordered a set of TBrown Dead Muppets. Even though you're not really supposed to use those kinds of windscreens without foam underneath, the "rats" were pretty effective for a couple windy outdoor gigs I used them for.
