Its hard to compaire a bounty on wild animals to animals people breed and keep as pets. If there was a bounty now every batch of kittens people are giving away in front of the store is worth $50 ea and every cat being given away on craigslist will be grabed up for a bounty. Some people will be breeding cats just for that purpose.
Bounties are still probobly a good idea because
60,000,000 cats X $50 ea = $3,000,000,000
80,000 pythons x $50 ea = $4,000,000
10,000,000 dogs x $50ea = $500,000,000
it totals less than 4 billion dollars witch on a scale of the checks the goveronment is writting lately is a drop in the bucket.
Think of how many unemployed poeple would be out catching cats dogs and pythons all over the country.
