can cats tell when another cat is sick?
Puffy had to be put to sleep back in June, but she was sick for a while- we took her to the vet and were in contact with the vet on the phone for a few months, but they weren't able to find out what was wrong with her until it was too late- there was a large tumor on her liver that they didn't see in the x-rays from 6 months earlier. They weren't sure if it was cancer, but they would have had to do the surgery either way, and they didn't think she'd make it through.
Anyway, the last few months of Puffy's life, her sister (litter-mate) Callie was increasingly mean to her. Near the end, Callie would hiss at Puffy for just walking into the room. She would slap her out of nowhere (and then they would box, which always makes me laugh, but it was also upsetting because Callie was always the one starting it). Callie never actually hurt Puffy physically, though. But I think she must have been hurt emotionally.
But after we found out that Puffy had cancer (not confirmed, but suspected from the tumor), I remembered that some animals can smell cancer. I saw on "Unsolved Mysteries" one time a long time ago about a dog that could sniff out skin cancer. And there are dogs who can sense when a person is going to have a seizure, too. Anyway, I was wondering if it's possible for cats also to smell cancer, or have some kind of sixth sense about medical conditions. I know it was internal- not like skin cancer or anything like that, but I still wonder if Callie somehow could smell cancer and it made her act that way towards Puffy... or if maybe the signs she saw of Puffy's sickness somehow bothered her and made her shun Puffy.
Anyone have any input?
It's just something I'm curious about.
