# Smart Home Pet Feeder Guide

`action.devices.types.PETFEEDER` - Interactions with pet feeders may include dispensing pet food or water in various quantities and presets.

This type indicates that the device gets the Pet Feeder icon and some related
synonyms and aliases.

## Device capabilities

Refer to the corresponding trait documentation for
implementation details, such as attributes and states that your service should support, and how to
build EXECUTE and QUERY responses.

### Required traits

These traits and commands are required, if applicable to your
device. If your device does not support these traits, enter the error code of
`functionNotSupported` in a QUERY or EXECUTE response. See
[Errors and exceptions](https://developers.home.google.com/cloud-to-cloud/intents/errors-exceptions) for more info.

- [`action.devices.traits.Dispense`](https://developers.home.google.com/cloud-to-cloud/traits/dispense)

### Recommended traits

These traits are recommended, if applicable to your device.
However, you are free to mix and match from all available traits to best match your existing
product functionality.

- [`action.devices.traits.OnOff`](https://developers.home.google.com/cloud-to-cloud/traits/onoff)
- [`action.devices.traits.StartStop`](https://developers.home.google.com/cloud-to-cloud/traits/startstop)

## Example device: Simple pet feeder

This section contains example intent payloads representing a common "Pet Feeder"
based on the device type and traits above. If you add or remove traits in your implementation,
modify your responses accordingly to reflect those changes.
