How Long Does it Take for Food to Digest? Angel threw up her kibble in the carrier we took her in to the vet's, so I assume she got carsick for the first time. I fed her at 1:15 p.m., and we left my house about 4 hours later. The food wasn't digested. It just looked softened like when it has been soaked in water. How long does it take for them to digest their food? |
