"The situation has worsened since our last mission in April 2015," Dr. Amir Khalil said in a press release. "According to estimates, there were still 40 big cats in the summer of 2015. Now, it is said that there are only 15 left."
Because of bad weather and ongoing conflict, there have been no visitors at Khan Younis Zoo, which means that the privately kept zoo does not have any income.
"The idea to mummify animals started after the Gaza war because a number of animals like the lion, the tiger, monkeys and crocodiles died," Awaida told the Associated Press in 2012.
Despite being small - just about 28 square miles - the war-torn area is home to six zoos, according to Four Paws. The organization is working on formulating a longer-term solution for the suffering animals in Gaza, while also trying to provide urgent care to the starving and sick animals.
And rescue work doesn't stop at the Khan Younis zoo. "The Rafah Zoo, which houses four lions among other animals, has been supplied with food and medicine," Claire LaFrance, a representative for Four Paws, told The Dodo.
LaFrance added that this is the first time Four Paws has used a crowdfunding platform to raise money to help with the food delivery and care - and the support so far has helped the animals tremendously. It has already raised $12,000 from animal lovers all over the world.
"Due to the overwhelming support that has flowed in, I also got word that it is very likely we can also help a third zoo, the Al Bisan zoo," she said.
