Catching an escaped rodent
Position a bucket or similar such as a storage box on the floor in a room that you think your pet rodent is in, making sure that the bucket is escape proof, you could also add another bucket to other rooms.
Next, construct an access ramp that leads up to the rim of the bucket making sure that it is sufficiently secure enough not to be knocked over by your pet rodent — you could use books and place them on top of each other as if they were a staircase or even better if you have tubes, you could lead them up from the floor into a bucket or other container.
Include plenty soft toilet paper inside the bucket for a soft landing. Place a selection of yummy treats inside also, making sure the treats are something which your pet rodent will enjoy – adding a piece of carrot or similar is also a good idea in case your pet rodent is thirsty. Adding an item of food that is smelly and loved by your pet rodent is a very good idea, this will help to encourage him to climb and seek it out. You could add a few sunflower seeds on the make shift ramp to encourage him to climb.
The idea of this method is once your pet rodent has climbed up the ramp he will drop down into the bucket and not be able to climb back out. This method does not always work and usually pet rodents are found before they get the chance to investigate this method of catching escaped pet rodents. Bear in mind, this method is far easier for trapping mice, rats and hamsters — gerbils are able to jump out of the bucket, but it is always still worth trying.
Putting the cage on the floor of the room you think your pet rodent is in is another good idea, hopefully when you return to the room, you will find your escapee safe and sound asleep in his bed.
If you are trying to establish which room your pet rodent is actually in, you could place a specific quantity of peanuts and/or sunflower seeds in each room and closing all doors. You then can come back later and see if any of the nuts and seeds have been eaten and this will give you an idea which room is being occupied.
