How can i keep stray cats off my front porch. my dog has gone through the screen door twice in three days.
Tie the dog up on the front porch :-)
Hook a sprinkler up to a motion detector.
Squeeze a lemon around the perimeter of your porch cats don't like lemons.
Ex. -8 x 8 = -64 because: a negative(-) times a positive(+) is equal to a negative(-) because unlike signs = negative(-). Just multiply the 8 and 8 normally. Hope I helped :)
