Direct answer: no—dog food should not be used as a cat’s everyday diet. Cats have species-specific nutritional requirements, so choose a complete food labelled for cats and the appropriate life stage.
Do not turn an accident into a routine
A cat stealing a little dog food is different from being fed it repeatedly. Return to the cat’s normal complete food and prevent shared bowls becoming the default feeding arrangement.
Separate feeding areas
In a mixed pet household, feed animals in places you can supervise and remove leftovers after the planned meal. Separate stations also make it easier to notice who has eaten and whether an appetite has changed.
Call a vet when the situation is not simple
Contact your vet if your cat has eaten a large or unknown quantity, seems unwell, has a medical condition or repeatedly refuses their normal food. Do not try to “balance” dog food with supplements yourself.
