Avajoy, Gio, my Bo is absolutely unafraid of the vacuum, probably because her previous owner used to clean her room with a handheld one (Dust Buster).
Bo's 5 top dislikes....
1. Being left alone while her humans are at work.
2. Being displaced from her favorite chair when I want to sit down.
3. Perfume/cologne and hand lotion.
4. Being handled too roughly (my dad likes to play rough and Bo hisses at him when he tries to play with her).
5. Sudden loud noises (dropped dishes, the coffee grinder, etc.)
