She is maybe 2. We have another female. Her sister and a male. She can stand. She tends to eat an drink very little. Started about a week ago. Just getting worse. I seen 2 cats outside today which are strays. I'm wondering if she got attacked? She has no strength in her neck
You'd typically see signs of an attack by a cat because they use their claws and teeth. You also wouldn't typically see progressive worsening from an animal attack unless it caused an infection. Do you mean you always eats and drinks very little, or only since this started? Does she seem to be in any pain?
Please send us anything you can think of from the time this started. Are you able to take her to a vet? Things like this can be very hard to guess at.
