Rats Sniff Out Danger & TB. Dogs Of War. Maliha's Update. Cargo Trailer. Kitten Manicures.

For "Mammal Monday", let's look at these clever little critters:

Rats save human lives.

Meet the Hero Rats who love to play hide and seek amongst landmines and unexploded bombs, and treasure hunt for positive TB samples.

"Apopo, a Belgian charity is harnessing the sociability, enthusiasm for repetitive tasks, love of bananas and acute sense of smell of the African Giant Pouched rat to uncover killers.
Working in Mozambique and Tanzania (with plans to establish operations in Colombia and South East Asia) Apopo has already cleared large areas of unexploded ordinance and detected TB in hundreds of samples missed by more costly conventional testing"


"Rats Sniff Out Danger in War Zones, they may be pests in a house, but in a war zone, these rats can be lifesavers.
Trained rats can sniff out TNT in landmines. The rodents are trained through Pavlovian conditioning: a click sound to signal a food reward whenever they make the correct detection.   It takes nine months of hard work before a rat is deployed for mine detection.

 A baby rat in a tiny red and black harness twitches its pointed nose incessantly, probing a grassy field where it is being trained by a pioneering Dutch NGO to smell out deadly landmines.
Other rats trained under the same scheme have already helped clear large swathes of land in neighboring mine-infested Mozambique.

Babette, the two-month-old baby, walks unsteadily across the weedy patch followed by two trainers rolling a bar that teaches her to go back and forth across the patch in straight lines.

Light, with an acute sense of smell and easily motivated by food rewards, giant African pouched rats have been found to be highly effective in mine detection by APOPO, the Dutch non-governmental organization that launched the training project -- the first of its kind -- in this Tanzanian town.

The rodents are trained to detect the TNT in landmines through Pavlovian conditioning: a click sound to signal a food reward whenever they make the correct detection.

Training begins at four weeks old when the baby rats are exposed to humans to rid them of their fear of people and new surroundings, after which they are taught to associate a click sound with food.

Once that is achieved, they are then trained to distinguish TNT scent from other smells. When they successfully distinguish it, the click is sounded and they are given a bit of banana, thus reinforcing the link between positive TNT identification and food.

In all, it takes nine months of painstaking on- and off-field training for a rat to be deployed for mine detection.
"This work is not easy," recounts trainer Abdullah Mchomvu, holding a rat cage under his left arm. "You have to be patient. Sometimes I get frustrated, but then again I tell myself these are animals."  But "this work saves lives," he added.

It takes two de-miners a day to clear a 200 square-meter (2,150 square-feet) minefield, but if they work with two rats they can sweep it in two hours.

"Detection is the most difficult, dangerous and expensive part of mine action. Since rats are much easier to train than dogs, rats in this environment are much more appropriate," said Bart Weetjens, the founder of APOPO.  "They are very effective. We have very high success rates. So far they have helped re-open almost two million square meters (21.5 million square feet) of land" in Mozambique.

Despite their contribution, rats are more often seen as vermin that spread disease and destroy harvests.
"Rats absolutely have an image problem. People don't like them and that is one of our biggest struggles," said Weetjens. "We are trying to change that perception. Rats are very sociable, very intelligent highly likable creatures."
APOPO calls its sniffers "hero rats" in recognition of the work they perform.
The organization's website pictures rats that could be straight out of Beatrix Potter: all pink noses and quivering whiskers. 
APOPO has even launched an Adopt-a-Rat scheme where individuals and corporations can contribute to the upkeep and the training of a sniffer rat, receiving in exchange an adoption certificate and email updates on the animal's training or career.

Weetjens said the next frontier would be to use the "hero rats" to sniff out narcotics or to search for survivors of disasters such as earthquakes or collapsed buildings."

Scientists Using Giant Rats to Diagnose TB

"APOPO trains sniffer rats to detect explosives and diagnose disease. This unusual idea has been developed into a competitive technology by a group of Belgian and Tanzanian researchers and animal trainers. This video demonstrates the use of sniffer rats to detect tuberculosis in human sputum samples. This method is far more cost-effective and efficient than other methods, including using lab technicians."

Here is how they are trained:

Maliha's Update:
Maliha is now recovering from surgery after being badly abused.
August 19, 2010:  Maliha, the three-year-old dog found horrifically abused.   Maliha's story was featured on Global News earlier last summer after rescue groups were told that her head was covered with a bag, and she was beaten with sticks by a group of people.
The beatings and abuse left her with a crushed nasal cavity and infections.
"I am a very sweet dog and I don't understand why anyone would want to hurt me so badly and then leave me to starve. I'm so grateful to have been rescued! I am the reason animal rescue groups have to exist.
Why…..How could someone…..I can’t believe….Oh your poor face…..What a sweet dog……Oh my……Why???    In disbelief, kind voices keep saying these words to me they are sometimes accompanied by tears, but always filled with compassion.
I have a severe infection in my mouth and nasal cavity, I struggle to breathe and eat. Yet even with all this I have an inner strength and calm beautiful nature. Foster Mom says she would understand if I hated people, but I show her with my every move that I will not judge the majority of people by the actions of a few who - while fighting their own demons - took things out on me. Forgive and look forward is my mantra and I will continue to live by it. "

March 2, 2011 update - Message from Maliha’s Foster Family – "There is no good way to deliver the following message. Despite the best efforts of everyone involved – Maliha’s surgery to repair the holes in her mouth was not successful.
There is no clear reason why, but likely a combination of the extremely large holes, the fact that she had the previous surgery, and most importantly the way she breathes with her broken nose likely lead to the failure of the cartilage bridges. Her veterinarian care team is as disappointed as we are. From the beginning we have known that her complete recovery was a long shot and we have come to the end of the road with an unfortunate outcome.

Maliha is still Maliha, she is healing from the surgery and doesn't know anything has gone wrong. She had holes in her mouth before and she still has them now - her personality and her attitude haven't changed. Now we must play out the hand she has been dealt and make the best of Maliha’s reality.

It is now up to us to use the lessons Maliha has taught us to make a difference in our lives and our communities. I know so many people have followed her story and will feel a loss at what has occurred, I am so sorry I do not have better news to share  – I thank everyone for their support, kindness, and care for this sweet little dog and hope her story and her journey has brought something positive and meaningful into your lives.

March 14, 2011 – "Well, I am feeling better these days. Those surgeries take a lot out of a dog and require quite a bit of recovery time. Foster mom says nothing is ever easy for me, but I think that is okay because lots of things in this world aren’t that easy. 
So here’s my update:
Ears feeling good and all healed up infection seems to be cleared - just finishing off my second round of antibiotics, and we will see what happens now
Mouth, surgery site is healed and, well, the holes are still there and they are going to be there… so I’m working on keeping the food in my mouth and not my nose, and pain… what pain?
I am off my pain meds and I am happy.  
If you can, please donate to SCARS so they can keep saving wonderful dogs like me." From Maliha.



This morning it was drizzling when I called to see what time Jay would be ready to be picked up.  He said it was 'pouring cats and dogs' at his house, and he was scared he would melt, so didn't want to work.
SAM_0824-1So Ray and I worked on the cargo trailer.  It stopped misting as soon as we started, and the sun came out.   Ray primed some more of the cabinets in the cargo trailer.  It is easier to prime and paint the sides of the closet, front and back, before they are installed. 

I vacuumed the trailer, emptied the shop vac, and my Hoover Nanolite, that I use in the house. They both sure do pick up a lot.  That Nanolite picks up all the grit, dirt and fur out of my carpet. It is the best little upright that I have ever had, and it is so easy to empty, and clean it's HEPA filter. The filter comes with a knob that you slide back and forth, and all the dust comes out.

For the little orphan kittens, with their Velco-like little claws,  it was "Manicure" time, today.

We met a guy while on vacation who is planning on working on a stealth cargo trailer too. I shared with him your website and also Mobile Kodgers for the past files to reference.

That picture of the kitty is so cute. I wish we could do Rusty's, but he won't have it. I am going to take him to our Vet when we get home.

Thank you for your comments, Karen and Pidge.

Karen, I am not going to put solar on mine like Randy did. I am going to let whoever buys it make their own choices.

Pidge, That is why I am starting these babies out young. They have to get used to having their little claws tipped every now and then.
