Jim has lost a second one too, but since I had the extras I just keep putting tham back on.

I may be deciding on new colors again. I was figuring out price for 10 cats $$$ But if I buy them in bulk I can get them cheaper, but I'd need to get a single color. I think I like blue on at least 6 cats, red on 3 or 4 (I may keep Kim in pink)

Here is another place to go and they offer all of the colors.

and in their printed catalog there is even a discount for quantity (3 of the refill packs would drop from $33.95 to $30.55) and with 10 cats, I'd probably have a 5 month supply after my first order. (Or something like that)
