Yup! It doesn't matter if an animal is expensive or not, they can be discarded. Someone released a savannah cat (serval x domestic cat hybrid) in the streets recently and there have few incidents of wolfdogs being released in the wild. Savannah cats and wolfdogs are usually very expensive animals. Not too long ago, I got a call from a concerned farmer about a Wagyu bull harassing and breeding his registered Angus cows. Wagyu cattle are not very common breed and super expensive but apparently this bull's owner don't want him and the bull is on his own. I had to pick up the bull and sold him to a hobby farmer that needs a bull that throws small calves. I got his daughter when the bull was living on my ranch and bred to two heifers of mine.
