Intrigued though I am about a housecat who looks like a tiger (I love tigers), do we need another cat breed? This stuff concerns me, as new breeds are bred for profit, and usually not with regard to health problems that could result. I hope this next part does not offend anyone, but here goes:
I will not pay a breeder to create another cat or dog, when there are so many languishing in shelters; many of which are kill shelters. These animals can make wonderful pets, and, in my experience, usually do. I take in strays and hard-luck cases (some folks say I'm a head-case for doing it!). I know so many people who claim they are "real animal lovers", yet won't accept anything less than a purebred or status pet. Yet, I think that it would be tragic if breeds died out. I've never knowingly had a purebred pet.
I think it'll be very hard for Backyard Breeders to jump on this bandwagon. The BYB's always buy/breed substandard cats and sell them cheap for a quick buck. I do believe a substandard Toyger will look like any other Mackrel Tabby. Why would anyone want to pay a breeder for a cat that looks like a DSH tabby they could pick up at the local shelter?
The health problem issues are mostly known already and have already been dealt with, since the primary cat used to create this breed is the Bengal. The Bengal cat has been around for four decades and is a healthy robust breed.
I think it's important to have responsible pet owners at all points in the spectrum. People who take in the hard-luck cases, people who give homes to shelter cats, people who have moggies and purebreds and people who only have purebreds.
The Toyger will have a personality identical to the Bengal. An outgoing, curious, playful, very affectionate, nearly fearless, extremely athletic, owner oriented cat that has an exotic look like a mini-tiger, with a pelt that feels like velvet.
There will always be people that want a breed cat, because it's very predictable what their behavior as adults will be like, not to mention the looks aspect.
I have seen Toygers in person at the cat shows I attend. Right now they are just being shown as exhibit and are not allowed to compete. To me, they just look like a bengal cat with stripes instead of spots. So far, I've only seen one Toyger that impressed me, he had the fanned out in the middle stripes that you see on Tigers, but his color was all wrong. He had the rufous coloring of a bengal, and of course his head still looked like a bengal.
They've got some major work to do, but I do think the breed is off to a good start, because the base cat is the bengal and this cat has already been proven to be a viable healthy breed.
