Why Why Why?!

It puzzles me more and more that Cathay has still not come into estrus. Over eight months have passed since she was separated from her sons JenB and Coco. We have been informed by various sources on the estimated time it would take for a tigress to come into estrus after separation from her cubs. Shanghai Zoo, with one of two largest breeding population of South China Tigers in China, said it normally takes two to three months after cubs are taken away from her, usually when the cubs are three months old. Other source says records taken from captive cats show a range of 75 to 592 days. Still another says it takes seven months.. It is very difficult to observe such events in the wild, so our project could be an ideal platform for finding out the situation with a wild tigress.

Anyway, we have done all we could. We moved her far away from her cubs so she could not see them for quite a while. We let her hunt for a few months to "forget" about her cubs. Having exhausted all available strategies, we decided to separate her from TigerWoods for a while, and putting her next to 327. I recall how excited she was when she first met 327 two years ago, chasing him around in the most enticing posture, and it might just take 327 again to excite her system. Some tigers seem to need just the presence of one potential mate. But other tigers are more like cheetahs, who would only come into estrus when there are more than one male present.

Cathay is such an intelligent cat. She seemed to know what we had in store for her and it was easy to get her leaving TW behind, and crossing three gates into the camp adjacent to 327 on April 29. New smells abound, as Madonna and her cubs spent quite a while here. Cathay was absorbed by the smells, busily sniffing and spraying.

May 4th, we let Cathay into 327's camp. We did this with much trepidation, as I still recall how 327 was terrified of Cathay and how they might end up fighting if he defends himself. To my complete surprise, 327 was extremely friendly to Cathay! All this year and half of life in the wild and in solitude may have served him well that he certainly became more of an gentleman. The two played a few games of hide and seek. Seeing nothing harmful happened to them, we decided to let them overnight together. Next morning, we came to see if anything dramatic had happened and were pleased all remained calm.

TigerWoods, however, are not very happy to be left alone. For several days, we heard him roaring, either calling for his mate Cathay, or complaining to us about being left alone. He refused to eat any food. Isn't this an expression of love by TW for Cathay? I don't want to be accused of endowing human emotions and values on animals but our evolutionary paths were the same throughout most part of our development. We must share similar emotions with other mammals. In the end, after a few days of hunger strike by TW, we did not have much choice but to decide to switch Cathay back and forth between TW and 327.

Meanwhile, King Henry and Princess are getting more comfortable in the 42 Ha camp, exploring further afield from the riverside area. For two days, after they made two kills, they even refused to come out. I was beginning to worry that the antelopes might have done damage to them. I was also worried that I might not see them for a while before I would leave Laohu Valley on May 10th. In fact, I made a bet of 50 US dollars with my friend  who came to visit during the weekend of May 8th, that they would not come out during our last afternoon drive. The sun was setting and I was about to drive out of the hunting camp and win my bet, when Vivienne spotted the silent appearance of King Henry! His demeanour had changed. Instead of making grandious announcement for his appearance, he quietly approached, as if stalking us. This made me more convinced that he made at least one kill this time, and was continuing to practice his successful hunting techniques now. I was relieved to see him, and to see he was intact.

Then, as if to grant my wish, Princess also peeped her little shy head from behind the tree branches, just when I started my truck's engine again. I was pleased that I had lost my 50 dollars completely by now, to say the least!!

I left Laohu Valley happy, but looking forward to my next visit again in a few months. So I still find no answer to Cathay's estrus mystery, except to say that she may be needing a rest after carrying two litters of cubs so close to one another. Madonna mated last year around this time. So if tigers do mate seasonally, as some say, Cathay should be mating now. May be soon? May be never? Maybe she will just keep me wondering why!!!
