The relationship between cat and child can be many years of happy Union real friends, or they can be fraught with complications or even physical violence.
Children often cannot recognize the signals the cat is sending them, requiring a inviolable personal space, whereby the animal may scratch the baby, and both will be upset or scared. This applies not only to kids or overly friendly four year old children who do not know how to handle cats, this also applies to children of all ages and even teenagers. Properly interact a child and a cat, depend on their physical safety and emotional well-being.
To help the child and the cat to get the best responses to each other, it is very important to set boundaries for each of their interaction.
