I have 3 cats: One older spayed female of 12 years, seemingly healthy, uses tray and maybe a bit podgy. Had her with one of her litter, she sadly got run over in 2002. One our own ( with my son) and then we adopted a ginger tom. He settled in well, apart from cat fights. He sadly got killed by a dog next door ( who has been dealt with by police dangerous dog department. I got 2 no 7 month old kittens, whom are now 8 months by my guess.. Been a month and some. Usual behaviour at first, still get poo's behind the tv. Both been in and out of season ( vets appointment end of the month). My older cat chases and hisses at them both, only the bigger of the two kittens is more assertive. She still runs off , now my older cat today sprayed behind my tv, where the other kittens had accidents or situations ..hehe. Is the spraying normal for my older spayed cat, a sign of territorial behaviour or her getting old/ill?
