My girlcat is nine years old, and is the most incredibly nervy, skittish cat I've ever known. She was a semi-feral farm kitten, and as we also live on a farm she's never had to get used to strange people, or a lot of noise or traffic. She took a while to settle with us but has been fine, and even learned to tolerate our dgs after a couple of years.
However, about three months ago our farming neighbours were doing some construction work which meant heavy vehicles and strange men in the field next to us, and around the house. She found this so traumatic she went missing for three days, and after she came home she spent a lot of time - all these weeks! - under the sofa, when indoors. She was/is stinking, but I put this down to her having been hiding out in the nearby cattle byre.
In the last few days she has finally become her old personality again, and I've been able to pet her, but she's plainly ill. She's always drooled when asleep, but now she drools a lot; her saliva is thick and is the real reason she stinks. She can't/doesn't groom herself properly; her "brother" has helped, but so enthusiastically she's now bald around the side of her mouth from which she drools. There seems to be a reddish, raised lump on her lip. She also has sore looking bald patches on both of her front legs, where she's drooled on them. She's a stinking mess, in short.
Up until about three days ago she was still eating fairly normally, (biscuits) but this seems beyond her now, and the weight has dropped off her. I've tempted her with treats she enjoys (scrambled egg, tuna; she's fine with dairy products and went wild trying to steal milk I was drinking, which isn't like her) and she's eaten some, (and drunk a lot of milk) but not enough to get weight back on. She's going to see the vet tomorrow, and who knows how much that'll traumatise her; she hasn't been since she was neutered as a kitten, never had fleas or worms (she doesn't seem to hunt, has never brought anything home) and doesn't come into contact with other cats so I've never seen the need for vaccinations. I don't want to subject her to a lot of invasive tests or treatments because that would seriously freak her out, and be cruel.
It's a PTS case, isn't it? :(
