If it's any consolation, I've heard of a story of a cat in a nursing home who would go to a dying persons room and nap with them. This would then give family enough time to say goodbye. The cat would otherwise not go and visit any of the patients in such a friendly manner.

So do I think you are crazy???? No, but I do think that animals have this innate ability that we don't know about, perhaps because we've lost touch with our senses and so many of us can no longer tell? Although it doesn't sound scientific, I bet it is!
As for Dove vs Pigeon, this is what I've found...
From the World Book Dictionary,
pigeon: any one of a group of birds with a plump body, short tail and short legs...There are numerous species, making up a family of birds. The smaller kinds are usually called doves.
dove: a bird with a thick body, short legs, and a beak enlarged at the tip. It is a small kind of pigeon that is not domesticated.
I think there is an important difference that I would explain to my students. As you can see from the examples below, "there is no true scientific difference." They both belong to the family Columbidae, but there is an important difference in how the two terms are used colloquially. Native speakers generally associate pigeons with domesticated birds or birds that fly around in parks and squares in cities. They tend to associate doves with wild birds that live in forests and are a symbol of peace. A love poem is more likely to have doves than pigeons.
Pigeons and Doves
There is no true scientific difference between 'pigeons' and 'doves'. While the smaller pigeons often get called 'doves', this is fairly inconsistent. The family can be split into two different groups, but this is based more on their ecology and diet. There are those pigeons that feed on seeds (usually duller coloured, ground-dwelling pigeons), and those that feed on fruit (more striking, aboreal species). The Daintree area has a diverse group of pigeons, with representatives of both types of pigeons, although many species are heard more often than seen.
"And you know what else really gets my goat? My Japanese students think they're DOVES for God's sake. DOVES, I said! They are NOT doves! Doves are pretty and white and they go coo-coo. They're gentle and lovely to be around. You'd never catch a dove stepping over another dove to get at a dirty piece of Pocky that some stinking kid who needs his diaper changed has a mind to throw at him."
"Don't you see! That's what's so dangerous!" Xavier says. "To confuse something vile and ugly, like a low and foul pigeon, with a gentle, tender dove ... it gets to the root of all the evil in the world! Every instance of evil! The deception in the Garden of Eden! Oh no, that's not a pigeon offering you that apple, Eve my dear! That's a dove! A lovely pure white dove who wants only the best for you!"
"Subtle semantic difference, you may say. Perhaps a pigeon IS a member of the dove family, some distant and unwelcome relative generally shunned at family picnics." Xavier digs into his pocket and slaps down a hundred-yen coin onto the metal drainboard. "But when people start confusing the two--innocently enough, but still, a confusion--the whole symbol becomes muddy. And when the symbols become muddy, can the idea behind the symbol ... can the idea of peace itself remain unsullied? You've got people confusing pigeons with doves! Pigeons are the most unpeaceful creatures I've ever seen, and that's my whole point! They've taken over Peace Park, and they've convinced everybody that they're doves. The wolves are at the door, and they're all in pigeons' clothing."
In all the replies, I don't think anyone has pointed out that the connotations of the word 'dove' are usually positive and those of the word 'pigeon' are usually negative. This is because the birds classified as doves rather than pigeons are usually prettier and have long been associated with love and peace. The birds classified as pigeons are nowadays generally considered to be a nuisance (except to people who like or actually keep them as pets!) and there are a few expressions including the word which also tend to have negative connotations, such as 'pigeon-toed', 'pigeon-chested', or even 'pigeon-holed'.
There's a similar thing with raven and crow. A lot of native English speakers would not be able to tell you the difference between the two - and indeed there may not even be a difference, But 'raven' sounds grand and striking and has a good connotation - conjuring up the image of the famous birds at the Tower of London and all the history and tradition - whereas 'crow' has a bad connotation and has even come to be used pejoratively about women (what a surprise!) to describe an elderly woman.
I don't know if this helps - but I really do think it's more to do with the associations of the words in question and how they are used than the scientific meanings when the two things are so similar that it's difficult to tell the difference.
Pigeons and Doves of the World
The above information came from a teaching/learning forum. Below is information on their family.
In general parlance the terms "dove" and "pigeon" are used somewhat interchangeably. In ornithological practice, there is a tendency for "dove" to be used for smaller species and "pigeon" for larger ones, but this is in no way consistently applied, and historically the common names for these birds involve a great deal of variation between the term "dove" and "pigeon."
