Best and cheapest way to retain cats
They are very freeflowing and pretty cheap. I've seen them go for cheaper, so you could wait and see what comes up. These don't say CARB for California, the ones I bought were, and were cheaper, they were the same brand. Maybe they make them different or can't keep up with cali regulations. At any case they work real well. You couil also reuse your old cats, by making the holes bigger cutting it with a sawz-all. I've done this and it works, but they are very heavy and restrictive, so I wouldn't do it. Just wait until you have the money.
