then i guess i might be wrong here...but yet again..do we know what sort of test applicable here in malaysia? for example..i will give u few cases.
1. PKD..yes PKD is genetic..confirm genetic..so we should not breed this gene pool...but incase that the kitten went to the new owner..and after 5 years, the cat having problem..so either die or seriusly ill, then the buyer went to the vet...so after post mortem or diagnostic...how do we 100% sure its PKD and not other kidney issue?not enough water feeding to the kitten/cat also can have a kidney failure...poison also can have a kidney failure..but of coz polycytic is genetic..but im saying as general kidney issue not only due to genetic..
2. HCM..its heart disease but there are more involving heart..not only HCM. we all know that not only HCM that can cause of heart attack..improper feeding by the buyer also can cause this in long term..same like if we human keep on eating too much those thing with high cholesterol etc..
the point is that...how do we know that the vet capable to prove that its really PKD when the the cat already die? how do we know if the vet telling the truth or just saying it out loud?does the buyer really want to do the autopsy or just pay some money to the vet to come up with the autopsy report? yes it is trust issue here ...
3. HD- yes the joint problem...but again..if the buyer keep them in very small area where the cat have very limited access for them to run, jump etc..then the muscle and joint will have problem..then again bring to vet and after the x-ray, found out the joint problem...so it is breeder problem again? excess of vitamin A can cause problem with HIP also.
i guess what im trying to say is that , 1.5 years of age is enough for a first stage filteration where the buyer will have the responsibility to go and check if there any genetic defect at that age..well its true that some will not have at that age but with report saying that the buyer did test when age 1.5 years then its a good proof that the buyer really serius about this and we as breeder can always help and support the case if it happen later stage.
also if we give lifetime warranty, then ppl will take for granted..so just wait until the end only making some noise..by that time it might be too late as maybe the gene line already been with many buyer already...
or what breeder can do also is that if got to know that serius genetic defect happen in that particular gene line, then the breeder can issue a notice to the buyer for recall. if the buyer decided not to return the cat then what else can the breeder say about it? (some may got too attach with the cat , so they dont want to lose them anymore)
conclusion is that the contract as just a guideline..and if the relation between the buyer and breeder is good, then it is good to use common sense..negotiate is the best way...like me..if 5 years down the road then i got to know that 1 of my line having problem...i dont mind recall them back and replace with another line..yet again..as breeder..it is the responsibility to test the stud and queen in the first place....
im not trying to make any argument here..just state my opinion..and i dont want to flame anyone...so pls..serius and honest discussion only...remember the target is to get a better line for the future and also educating the owner and breeder...

cheers
