Duct tape over the holes and Velcro strips on your cabinets should help, but remember that your ferret will show you what you overlooked, so watch him carefully when he first comes home with you. Children under the age of seven should always be supervised with your ferret to make sure it gets handled properly. Also, ferrets do not get along with small animals like birds, hamsters, guinea pigs, or rabbits. Some dogs get along great with ferrets, while others treat them like chew toys. If your dog likes to chase squirrels, then getting a ferret might not be the best idea.
Cats usually display haughty tolerance towards ferrets.
They might show some interest in the ferret at first, but generally, your cat will avoid the annoying new addition. You MUST be patient with a ferret. Sorry to sound so preachy, but if you kill a ferret, we'll hate you.
