Thread: Do Indoor cats really need Rabies vaccine?

Since my kitties just had their yearly rabies shots (this was the first year they did not need anything in addition to rabies), I watches them recovering for 3-4 days. Nothing dramatic, just more sleeping and mood changes.
I started wondering if it really worth it since my ladies are strictly indoor cats. What are the chances to get infected?
Can my kitty get the disease from eating the grass slobered by rabid racoon ?
