Lack Of Stools
The abscence of any stool for a 24 hour period should not be taken lightly. The most frequent cause of this is an internal blockage. This may result from the ferret's swallowing of a small piece of foam rubber or any other small object. Lack of stool especially accompanied by vomiting must be dealt with promptly.
Ferrets are simply too small to have enough body reserves to postpone treatment. It is frequently necessary to x-ray the ferret to locate the blockage and then go in surgically to remove it. The survival chances of the ferret are substantially higher if the operation is performed before the animal becomes weak.
Note: Any animal who is sick and not eating much will have little stool, but this does not indicate a blockage. It is better to check with your veterinarian early on concerning any potential problems.
