Lucy is very sweet but scared. She doesn't fear nip, but she'll put her mouth on your hands when you pick her up. She just needs lots of patience and someone who is willing to take things slow with her so she doesn't get scared. She LOVES my other two dogs and I would think she would do just fine with cats. I wouldn't worry about her with kids either, she just runs away if she gets scared. My 9 year old neighbor was petting her when I was holding her and she was fine. She is puppy pad trained when she's in her crate while I'm at work or at night. But if I have a puppy pad out around the house she doesn't understand to go on it unless I keep putting her on it. So she just doesn't understand potty training right now. But we are working on it! She's a total sweet heart and would be great for a calm older family
