HISTORY
In the past several months, many people’s African Giant Pouched rats have been
getting sick. No matter what treatment is administered, it seems once these
majestic animals get whatever terrible virus or bacterial infection this is,
there is nothing that can be done to save the rat’s life.
When it first started happening, we thought there might be some
connection to heredity, and I spent much time trying to see where the
connection might be. Now, after seeing it run through my own African rat
population, I am quite sure it has nothing to do with heredity, and is
definitely some sort of illness that they just can’t seem to fight off.
I lost my beautiful one year old, Tanzania, on March 5, then my sweet,
talkative, cuddly 4-1/2 year old male, Monster, on March 8. I thought it was
going to stop there, but it wasn’t long at all before Lyric and Gomez began
showing the same symptoms. I immediately started antibiotic treatment along
with fluid therapy, but nothing helped; their symptoms just kept on
progressing.
On March 23, I made it home from work just in time for my incredible
3-1/2 year old girl, Lyric, to take her last precious breaths in my arms. I
decided I had to do whatever I could for Gomez, no matter what the
consequences, since I still had one healthy African rat left and I had to know
if there was anything else that might stop this thing in its tracks.
When I awoke the following morning (March 24), I found Gomez with his
teeth clasped around the bars of the cage. He was almost totally unresponsive
and had blood around his mouth. I decided I couldn’t allow this poor rat to
suffer any longer and made the heartwrenching decision to euthanize him.
Morticia is still fine several months later, showing absolutely no signs
of this illness, and I pray that she will continue to be spared even though
she doesn’t care for being handled.
SYMPTOMS
The most visible symptoms with this illness are lethargy and shaking. The rat
closes his/her eyes and very rarely opens them again, if at all. If they do
open their eyes, it’s only a tiny bit. Their eyes almost seem to be sunken
into their head. They seem to quiet down and only vocalize when they are
touched, making me believe that they are in some pain, the degree of which I
couldn’t begin to guess.
The shaking is very obvious when you stand the rat on its feet. It
appears that all coordination is lost and they have a difficult time staying
upright. Also, while holding them like a baby, you may notice their feet
trembling.
All of my rats had a good appetite until a few days prior to their death.
They also tried to eat and drink when hand fed/watered, but couldn’t on the
day before their death. They would bite at the syringe when it was put in
their mouth, but were not able to swallow. Water would run out of their mouth
and down the side of their chin. I didn’t continue to try to feed them when
this began for fear that they would gag and choke on food.
Their stools were completely normal until a few days before their death.
I examined the stools looking for parasites, but saw nothing. A few days prior
to their death they began having loose stools, although they were not runny
and could not be considered diarrhea. I attributed this to me feeding them
soft foods, but I suppose it could have also had something to do with the
progression of the illness.
At no time did I notice a difference in urine output, although Tanzy did
seem to drink for long periods of time during the phase of her illness when
she was still active. She drank slowly, but for long periods of time, although
she did not drink nearly as frequently. Because Monster, Lyric, and Gomez
lived in the Office/Rat room (Tanzy lived in my bedroom), I was not able to
observe the frequency of their drinking. However, I did notice that the
illness did seem to progress faster in the older rats.

It is obvious that this illness is passed from one African to another through
the air. Tanzy was the first to become ill and she lived in a completely
separate room from the others, but three out of four of the others also became
ill and died.
The real question is: where did this illness come from and what is it?
Unless someone has a vet they can turn to and can afford serological testing,
tissue testing, etc., we will probably never know what it is. My veterinary
source for that kind of testing on an illegal animal was lost to me when I
moved from California to Massachusetts. Regarding where it came from, we may
never have the answer to that, either, without knowing what it actually is.
This illness has not only appeared in my African population here in
Massachusetts - it has emerged in several different areas of California. So
far, the only connection we can make is that all of the homes in which African
rats lived, who became ill and died, also had domestic rats as pets. However,
at this time there are still homes housing both African rats and domestic rats
in which this illness has not appeared. Also, I have had African rats for
3-1/2 years living in the same room with domestic rats with no problems until
now. Therefore, making any real connection with all of this is essentially
impossible.
CONCLUSION
Where do we go from here? At this point, I don’t have the slightest clue. What
I’m hoping from writing this article is that somebody will recognize something
and at least get an idea about what has been happening. I am much too close to
this one to sit back and make an objective observation. Anyone have any ideas?
