Take a look at the sentence again:
My cat Fuzz sprang onto the kitchen counter,
strode to the sink, and
flinged herself onto the cool porcelain
for an afternoon nap. Only here was she safe from the pursuit of Oreo, the
dog.
The third verb, flinged, is the problem. The sentence requires the simple past. Flung is the correctly spelled form.
| Verb | Simple Present | Simple Past | Past Participle |
| fling | fling(s) | flung | flung |
Sprang, the verb you chose, is perfectly correct. Before you continue, review the rules for irregular verbs.
