I would highly suggest, however, if you do put an ad out in a paper, please, for the safety of the animals, do not list them as free.
When I was in high school, I wrote for our school newspaper and I wrote a story opposing dissection. I had to do a ton, and I mean a ton of research and I found out that there are many Class B dealers who take pets they see roaming around, regardless if they have tags, and/or, they scour the papers looking for free animals to obtain for the sole purpose of supplying companies with animals to dissect. Especially cats.
I can't say how common this is now as I wrote that article over 10 years ago, however, it is (or at least was) a frightening reality.
Maybe ask around at work, or close friends or relatives to see if they know anyone trustworthy who would be willing to adopt your animals. If nothing else, I would recommend a no kill shelter.
I'm sorry you have to get rid of your pets, and, I do completely understand the frustration of them thinking the whole house is a toilet...That's the main reason I've torn up most of the carpeting in our house.
Good luck, I hope you can find them a wonderful home!
