Preferred Pet Solution.
You're not going to like this but I'll say it anyway, fully realizing that this very excellent piece of advice is likely to fall on deaf ears.
The best thing to do to ensure top price for your home is to relocate your pets while your home is on the market.
Putting them in the back yard, in the garage or in another room that you keep locked is insufficient, and it's not fair to them.
You need to remove them from the house.
Let a friend or relative care for your Pet during the marketing period of your home.
Board them at a kennel.
Send them on vacation.
