Hello to all!
Finally received our Silver Puppy!  We are CS newbies and have a colony of 
feral cats which we've occasionally heard hacking (upper respiratory?). They 
drink from one big glass water bowl. 

We'd like to add CS to their water but are concerned as 2 of them are nursing 
their kittens. Is it safe for these moms to be drinking it too? How long and 
how much should be added? Could it be added on a daily basis infinitely or do 
it on a schedule? Many other ferals come through, besides "our" colony which 
live in a "condominium complex".
Thank you!
Sam
