I have seven cats. Went two years here without snakes, then WHAM last week of may- first week of june 5 snakes, the first 2 were out where the cats dont go by one of my dogs, in the shed, the dog found them and would've ate them if i hadn't got them. Then, found one in house, it came in under house and must have come in the spot where my bathroom pipes run and the panel on other side of the pipes isn't totally covered since its inside a cabinent...lol. I got scared to death, the snakes waited till the week my mom was here staying to show their heads, 5am, and i hear "HEY HEY WAKE UP WAKE UP! GET IT GET IT THERES A SNAKE!!!!!!!!" I'm like geez. two minutes awake and i've caught 2 snakes before this one within the past week, and have no issues getting them bymyself...In the house, in the hall that leads to bathroom in question and stairs, with 'help' from a toilet plunger and my mom who was histerical because the snake was going towards my daughters room, and low and behold, i get bit with help.
Then two days later another black snake, and then two garter snakes, one scared me while working on my new chicken coop and run, it came out from under the shed i'm converting, and then another in the chicken coop.
But my cats will kill them, first garter snake wasn't but 2 ft and he got eaten by cats right after startling me. My cats dont like them, and the thing is cats don't necissarily kill them, though they will smaller ones, but larger snakes they will aggrevate the snake till the snake retreats. And cats also are controling the prey population around your home and yard, so a snake is less likely to come up, but i think with my chicks and eggs, the snakes are really interested this year, to many things to eat and not enough cats to protect 2 acres. lol.
