<human>: Can you succinctly summarize the text in 1-3 sentences?

My cat, Fluffy, is only 10-11 years old. She is a stray and we never did have enough money to take her to the vet for vaccinations or other things but we always fed her and treated her well. She got hit by a car about 6 months ago and while it hurt her hind legs and her tail, she seemed fine after a few days of rest (again, we couldn't afford to take her to the vet). She's been fine every since until last week when she disappeared a few days ago (she's allowed to go outside and spends most of her time there). She usually comes home every day for food so I was understandably worried. When she did come back, she lost a lot of a weight and she refused to eat anything with gave her. The next day however, she did take water. For the past 3 days, she's lived only on water and occasionally licking at tuna we give her. She's terrifyingly skinny but she still moves around and drinks water so I'm trying to squeeze out every bit of hope that she'll make it. I don't want to be selfish and don't want her to suffer but if she's still moving occasionally and still taking water, could she still be fine?
<bot>: My cat is not eating and only moves occasionally, but still takes water. Should I wait or put her to sleep?
