Hi Jackie,
I can kind of relate to your story. Everyone has such good suggestions about this. I am glad that your neighbors are being amiable about this. Good luck! I am in a similar predicament and am unsure of what to do. One of my best friends from high school is ...*gulp*...I believe an animal collector. Her heart is in the right place and I love her to pieces, but it doesn't do her or the animals any good. Not to mention the 6mo old baby that lives there! She has 9 cats (with only 3 litter boxes that are cleaned once a week! Yikes!) and 4 large dogs that are stuck in the backyard with no stimulation or interaction. I'm unsure of how to approach her without insulting her or hurting her feelings. I don't understand why she had to go out and buy the 4th dog, let alone keeping the other 3 in the first place. She is never home, and the dogs are basically ignored (a couple of the unneutered males have started to fight) and the cats are making messes on the floor in the house due to neglect of the litter boxes. Also, since I have moved, she's farther away, so I don't know what to do from long distance! Help!
