There are good and bad with everything. The genetic code is being increased with more offspring from more individual tigers, you will have a stronger genetic code. The question is animal quality of life. But ask yourself this. If a tiger is brought into the world to an abusive trainer, would that tiger rather be unborn? Hopefully we can rescue them when they are abused, but a living being is precious and always wanted in this world.
A tigon is a hybrid cross between a male tiger (Panthera tigris) and a female lion (Panthera leo). Thus, it has parents with the same genus but of different species. The tigon is not currently as common as the converse hybrid, the liger.The tigon’s genome includes genetic components of both parents. Tigons can exhibit visible characteristics from both parents: they can have both spots from the mother (lions carry genes for spots—lion cubs are spotted and some adults retain faint markings) and stripes from the father. Any mane that a male tigon may have will appear shorter and less noticeable than a lion’s mane and is closer in type to the ruff of a male tiger. It is a common misconception that tigons are smaller than lions or tigers. They do not exceed the size of their parent species because they inherit growth-inhibitory genes from the lioness mother, but they do not exhibit any kind of dwarfism or miniaturization; they often weigh around 180 kilograms (400 lb).
Thank you for your email. I do think that there might be more going on than stress, and kittens are prone to infectious diseases. If you don't trust that veterinarian that you saw, it would be a good idea to find a second opinion, even if you have to travel a bit to do so, as he could have a problem that needs to be treated. You can also call your veterinarian, let them know that he isn't getting better, and see if they have any other recommendations for him.
Kokwa may be breathing fast due to stress, pain, respiratory infection, heart conditions, anaemia (check gums), poisoning among other causes; without examining Kokwa and listening to the heart and lungs I cannot say specifically what may be wrong. You should keep a close eye on Kokwa and if the breathing doesn’t improve you should visit your Veterinarian in the morning or if you see he is in respiratory distress or his gums are white visit an Emergency Veterinarian immediately.

A normal cat should always breathe with small movements of its chest. If your cat's sides are moving a large amount, this can indicate labored breathing. Unlike dogs, cats should generally never pant. You can also try to watch for any increased abdominal movements with your pet's breathing. If you cat is breathing normally, you shouldn't see any excessive movement in the abdomen, or any hitch to the breathing.

My fiance said the he saw her eat this afternoon, so that is a relief. Her gums are pink (that's one of the first things I looked at on her and I should've told you that...but... this is my BABY CAT and she has me a little panicked!.. not like dealing with humans on the ambulance... she's innocent!) I do have access to oxygen... so we can make her an oxygen tent if it's necessary. Right now, she is getting up every couple of minutes and repositioning or pacing.. her respiration rate is around 50 right now... her belly almost looks like it's spasming and her heart rate is running between 80 and 90 everytime we take it... which is low... what do you suggest??????
