It is cute.
BUT...it is such a serious message, also. I am dealing with someone else's irresponsibility right now. I have two kitties that I have 'rescued' from a feral mother. One had to go to the vet immediately for infection. Over a hundred dollars later, he is doing fine.
They had fleas when I brought them in. My Sassy got fleas.

Frontline made her sick. I had to put her on steroids for the itching. We are just trying our best to deal with it all.
Because someone else was an idiot.
SPAY AND NEUTER! YES! YES! YES!
