Hi, I have 9 cats all together right now, 3 of which are only a month old. Out of all 9 there are only 3 girls. one of which is a baby. Not once has any of my unneutered males sprayed, and we foster alot because my hubby works with the animal shelter. so really it just depends on YOU specific cat. Dont stress to hard about spraying because ive never had a sprayer. but You should get your cats fixed, i learned the hard way with my kittens, and now i have a blood brother mounting his sister by blood so shes gettng fixed this month.
