I am positive that Casper has some Siamese in her somewhere. The blue eyes indicate that. And she is beautiful, not ugly. When prospective adoptees come to see her keep in this info in mind. The person should be willing and interested in a very interactive cat who might need more attention than the stereotypical cat they think of who doesn't need human interaction. My cats are both Siamese Mixes and exhibit all these traits. They are a full time job, they are my kids. Please try to find her a good home even if your mom is set to give her away.
Did You Know?
The Siamese personality is different from other cats in several ways. Siamese are very attached to humans. In ways they are more like a dog or an infant, in that they need much more attention than one would expect. They really require daily individualized personal time with you. They will follow you around the house, play games with you, and demand your company and attention when they want it. Unlike dogs, however, there is often a probationary period before they give you their total trust.
They are also highly intelligent. Because of this trait, without the personalized attention and some training they can get themselves into all kinds of trouble. They can go where they are not supposed to, open things that they shouldn't, be in places you don't want them to be - they can constantly be on the lookout for stimulation and if it's not provided they can make their own.
The voice itself is very different from other breeds, and can vary from a plaintive mew to a loud yowl. They are often mistaken for crying babies. The intensity of the vocalization should not be prolonged if you are smart enough to understand what they want. Most of the time they talk at conversational levels.
