To analyze the sleeping patterns of Malika's cat and baby, we can calculate the average hours of sleep per day for each.
1. **Cat's Sleep:**
- The cat sleeps 18 hours per day.
- Over a week (7 days), the total is:
\( 18 \text{ hours/day} \times 7 \text{ days} = 126 \text{ hours} \).
2. **Baby's Sleep:**
- The baby sleeps a total of 91 hours for the week.
- The average sleep per day for the baby is:
\( \frac{91 \text{ hours}}{7 \text{ days}} = 13 \text{ hours/day} \).
Now we can compare their sleep:
- **Comparison:**
- The cat sleeps an average of 18 hours per day, whereas the baby sleeps an average of 13 hours per day.
- Therefore, the baby sleeps fewer hours per day than the cat.
The correct response is:
**The baby slept fewer hours per day than the cat.**
