Thanks for the quick reply.
Yes, all these things had worried me.
These marmosets here were captive bred, the parents of jackjack were legally imported and microchipped from supposedly and hopefully legal captive bred parents. I realise that at some stage in the lineage that they were once taken from the wild, how far back, I am not sure.
Living in Asia, particulalry Bangkok, although not as bad as Indonesia and China, I do see illegal animals for sale. I have seen adult marmosets for sale here of which any legal proof of being bred here could not be provided. These were reported to the wildlife authorities but nothing was ever done.
Also another one called a 'slow loris', I have seen many of these babies for sale, the desire to buy them and take them away from the market and the small hot boxes they are kept in, is only defeated by the knowledge to buy one will mean it is only replaced again from the wild by another. these are absolutely the cutest little things on the planet.
Anyway, those are the illegal animals I would have loved to have given a home, but have not. This little marmoset was a different deal and the family that breed them, have been doing so for sometime and take great care of them.
I have had friends with monkies, but other species, gibbons and such and have heard their stories and particulalry about adult behaviour.
I intend to get a female for jackjack, so he has that company full time and can interact with his own kind. But I will wait 6 months to make sure all is well with this little fella.
The disease factor does worry me a little, I come from Australia, a country with very little disease problems and none of the nasties like rabies etc. I had kangaroos and various other animlas for years, healthy and relatively easy animals to look after, although as hand reared animals, still the same problems and effort required to successfully raise them as many others.
There are not really the specialist people here in this country to find easily to deal with these problems and get the info you need and have the tests done etc. A problem with living in such a country.
Can the marmoset be tested for some of the more dangerous disease, rabies and hepatitis as mentioned for example ?
Also as I read and as you mentioned, the common cold caught by them from us can kill them. What prevention of this is best, how easily is it caught by them. If being in the same house or area as someone who has a cold is enough for them to catch it, then how have they ever survived in any home ? how have they survived in zoo's with tens of thousands of sick kids and adults visiting them daily ?
As with everything, there are the horror storires, there are also the good ones, I am hoping jackjack will be a good one. For example, his recent bahaviour in taking to us, he will climb out of his little house where he sleeps for know and run around the table. he will come over and jump onto me and sit on my arm, wrap his 4 legs around and cling onto the hairs tighly and fall asleep. He thinks I am his Dad, i can walk around anywhere with him like this and he stayes hanging on and sleeping.
Granted with maturity, things change, as with any animal, even a dog. But responsible owners keep a pet for its life, not just the cutesy stages.
