You did bring back memories...
Our family belonged to several Beagle Clubs from the '50's to Y2K.
Talk about 'stray cats'!
Folks would dump off litters of half grown cats on Beagle Clubs.
These clubs were on back roads with their land boardering these roads.
Many times I would shoot 4-5 cats, same size, same color. I could tell they were from the same litter.
One club was infested with 'dumped cats' that quickly became residents.
I was contacted to get rid of the ferral cats.
I recall in a 2 month period...I caught 72 ferral cats in 2 live traps in the bottom of the barn. Plus there were other cats I shot and other members shot during the same time.
This cat problem still exists today for Beagle Clubs, but a much lower scale as yesteryear as UB stated about more folks giving to SPCA, plus spading and nueturing programs.
