There are reasons for those “This House is Protected by an Attack Cat.”
I owned an “attack cat,” it took 6 years to calm her down but I would never fully trust her around ....children.
Cat’s can have several kinds of seemingly unprovoked types of aggression. One is called transfer aggression (what my cat had) and the other is petting aggression (why I have a bite wound on my hand from a client’s cat). Cat bites and scratches are very bad deals and I sincerely hope they take the baby to the hospital or doctor.
This will provoke the removal of the cat from the home by the health department or child services.
No cat or dog should be left alone with a child under 18 months. By 18 months the child can fend off most cats. Extend the ban on dogs another year. Our ACD wanted to eat our granddaughter until she go big enough to throw a frisbie. Then and now he adores her and the only time I saw him get violent was at a man he thought was a threat to her. (actually he was right and chased him out of the house).
Our cat is a sneaky biter. She will be just playing; then she gets this naughty look in her eyes and we later find long red scratches on our arms. - We first named her “Lambchop”, then the neighbor kids started laughing and guffawing at us calling “Lambchop” (and she would never answer to that name anyway - we’d already tried “Zippy” - and the only name she would agree to answer to is “Brutus”). So, “Brutus” it is; I don’t like it, but that’s it. At least, the neighbor kids don’t make fun of it.
