Here's Echoweaver, back for another installment of the Pets Expansion Expansion.
This mod introduces four diseases (or five, depending on how you count). All can be caught by cats or dogs and are contagious between the two species.
As with Pet Fighting, This mod can be tuned to either allow pets to die of lethal diseases or, for those who don't want that kind of realism with their furbabies, force a pet into a long sleep to recuperate instead of dying. This is just a tuning value, but I've uploaded two flavors for download with death turned on and off so that folks can have the one they prefer without opening a package editor.
This has been a bear to test because all the contagion is based on probabilities. It's hard to be sure what odds are really going to be too little or too much in a real game. Because of that, I've included an extensive tuning resource Echoweaver.Sims3Game.PetDisease.PetDiseaseManager. If the diseases feel like too much or two little, you can change them.
Details of the diseases:
1. Germy: This is essentially a cold.
- Symptoms: Coughing with corresponding drop in energy
- Caught by: Being outside in rain or snow, with a small chance of catching from non-resident sims the pet just met. Cats have a small chance of catching it from fishing when the temperature is at or below 40 degress F.
- Contagion: It can be passed from sim to sim via proximity.
- In most cases, Germy expires, and the sim becomes healthy again. There is a 25% chance it will develop into Pneumonia.
- No cure and no vaccine.
This replaces the Germy moodlet that dogs can get. (At least, the wiki says dogs can get a Germy moodlet, and I've seen threads on it on several forums. I haven't seen it myself, but I usually play with cats.)
2. TummyTrouble: This is EITHER a virus or food poisoning.
- Symptoms: Periodic nauseous moodlets
- Caught by: The virus can be caught from meeting strangers, fishing, playing in the toilet, and eating trash. Food poisoning can be caught from eating human food (higher chance if it is spoiled) and eating prey.
- Contagion: Food poisoning is not contagious. Stomach flu virus is proximity contagious. There's no way to know which one your pet has except by observing.
- Can be cured at the vet. Cannot be vaccinated against.
3. Pneumonia
- Symptoms: Coughing, Wheezing (from dog panting), and passing out.
- Caught by: Having a Germy moodlet and being unlucky. Pneumonia always develops from Germy. It can't be caught on its own.
- Contagion: Currently not contagious.
- Has a 25% chance of being deadly if not cured at the vet.
- Can be cured at the vet. Can be vaccinated against.
4. Petstilence: This is inspired by rabies, but is almost entirely unlike it.
Actual rabies is just too awful to put in the Sims.
- Symptoms: Three stages of increasing behavioral symptoms -- excited, scared, and angry. At the second stage, pet starts drooling. At third stage, flies start swarming around the pet, and the pet may randomly attack other sims.
- Caught by: Low chance of catching from fleas or catching prey.
- Contagion: Fluid-borne. Can be caught from woohoo or fighting with an infected pet. The raccoon is considered always infected for this purpose.
- 100% lethal if not cured.
- Can be cured and vaccinated.
It also adds two human interactions:
- Take to Vet: On a sick pet that can be cured.
- Vaccinate Pets: On Hospital rabbitholes. This action can be performed on multiple pets from your household at the same time. You can't vaccinate pets that are A) currently vaccinated or B) currently sick. Vaccination lasts for one year.
