| Despite the persuasive evidence of dogs' prowess in these areas, the case of Oscar the cat is still a bit of a mystery, says animal psychologist Roger Mugford. Although they can detect illness, he has never known of pets picking up on impending death, and cats would be unlikely candidates to behave like this if they could. | Despite the persuasive evidence of dogs' prowess in these areas, the case of Oscar the cat is still a bit of a mystery, says animal psychologist Roger Mugford.

| I had a sick chicken a few months a go (we had 8 at the time) and thought it very odd when my pet cat sought out the chicken and curled up next to her - an hour or so later the chicken was dead. The cat had never done this before or since with any of the other chickens.sue, Hampshire | |
| When I was a child we had a spaniel. When she was a pup she was friendly with a Labrador along the road. As they got older they didn't see one another. Suddenly one day, our spaniel turned up quite out the blue at the home of the Labrador, was given access to the house, sought out the Labrador, sniffed him for a short time and came back home. Two days later the Labrador died. The houses were about a quarter of a mile apart.Mike, Edinburgh | |
| I have always had at least one cat, and have noticed how they pick up on my mood. If I am upset or ill, my cat will come straight to me to provide comfort. I even observed this with a cat we took in from a rescue shelter, who would not come anywhere near me when I felt well! I think it is more extraordinary for a cat to do this (and they clearly do) despite being independent creatures, whereas a dog is dependant, and it is in their interest to keep their host happy.Jane, Kent | |
| Cats also show an empathy for people who are suffering a bereavement. When my father died, and my mother came to stay with us, both our cats would not leave her side and even slept on the bed with her, something we don't normally allow, but we could see the comfort she was getting from them.Helen Waite, Appleton, Abingdon, UK | |
| My family cat, also called Oscar, almost predicted our family dog's death. She had been ill for some time and we decided to have her put down at our house. Oscar and the dog had never been particularly friendly, but in the hours leading to her death, Oscar never left her side and was cuddling her. I don't know if it was psychic or due to him being able to tell biologically, but it was nice for the old dog.Hilary, Edinburgh | |
| I have known cats to behave in this way. When my mother was dying of cancer her normally aloof British Blue cat spent almost 24 hours a day lying next to her on the bed. More recently, when I was laid up earlier this year with glandular fever my two cats who never normally stay in the house during the day spent three days snuggled up with me on the sofa. I have also owned boxer dogs in the past, both of whom would spend hours cuddled up to whoever in the household was under the weather.There doesn't always need to be a logical explanation for these things - sometimes they just are!Jane, Preston | |
