I completely understand. You do all that you can possibly do for them all , but sometimes, it is just IMPOSSIBLE to help them all. I know how hard it is to just say I cant do it right now, BUT dont ever feel bad for the work that you have and do continue to do. Think about it this way, Look around your house, see all of those cats? I am pretty sure none of them would be as happy anywhere else as they are with you. You spend time with them, provide food/shelter/medical care for all that you can. Who could expect any more than that? I would never look down on ANYONE who does all that they can, you do more than most! I dont/am not able to take anymore in at this time, and I feel bad, BUT I know that I have made the ones I have lives better, and I feel good for that. And you are right, it is DEF. better than a trip to the pound. And I am sure you know by now, that some people will say anything they can to make you feel bad/guilty to get animals off their hands, ya know? Dont always believe what people say, because who knows what they are trying to pull.
And for the seperation of animals, you cant help that. I understand and I am sure everyone else knows that when you rescue, sometimes serperation ISNT an option. It is better than being outside or locked in a bathroom with cages stacked onto each other. You do your best, and I hope that you know that. I do.
