My cat ate a mouse. What are the dangers and emergency signs?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 10 lbs

I was outside last night and heard my cat meow. She always replies and comes when called, so when I got a funny sounding response and she didn't come, I went looking for her. I found her underneath my neighbors SUV, she had caught a mouse and she was eating the last bit of it. She's not acting herself and I'm concerned that something may be wrong. What dangers can come from her eating the mouse and what should I watch for if it turns into an emergency?

She was doing her natural animalistic behavior when she ate this mouse. However, mice can carry disease and can just make a pets stomach upset. It sounds like at the very least she has an upset stomach. You can try fasting her for the next 12-24 hrs and then feeding her a bland diet of boiled plain chicken and rice for a few days to see if this settles things down. If she is severely lethargic, not responsive when called and she is indoors, has pale gums, has continuous vomiting episodes, or any neurological symptoms (drunken walking, falling over, etc), then those are more serious signs of toxiicty and she should be seen by your vet right away. If she also just doesn't feel well and hasn't recovered within 24-48 hrs, she should be seen. I hope that Swiri feels better soon. In the meantime, it is best to keep her indoors. Best wishes and take care.
