My oldest cat, Lucy (age 19) has a damaged front leg. We got her as an emergency rescue 12 years ago. I was only supposed to look after her for one night. I fell in love with her as soon as I saw her
The tendon in her leg is severed (a result of being used as a football by her previous owners) and she had probably been like that for some time. The day after I got her (I decided as soon as I saw her that she had a permanent home with me), I took her to the vet to see what he advised. In her case, I had two choices. Either get her leg amputated or keep her as an indoor cat only. Lucy does have some use of her leg, although it is withered. She walks on the back of her paw. Most times she holds it up but uses it to wash her face, dig her litter box - and pull my hair to wake me up
Lucy gets on fine the way she is. She lives in my bedroom as she doesn't like my other cats except one, Snowy. She is very close to him so just about everything is nice and soft for her so she doesn't hurt her leg.
In your case, your little cat has no feeling or use in her leg and it will only be a hindrance to her and possibly end up causing more injury so I would say amputation would be the best option for your cat. Be guided by your vet and as others have said, cats get along fine on 3 legs.
You've done a wonderful thing rescuing this little cat
You'll find she'll be the sweetest, most loving cat you could wish for. Rescued cats very often tend to be more loving. I'm sure they know. Lucy's got me wrapped round her little claw - and she knows it
her to bits
PS. You have a gift from our Lucy.
