hello, new here. my cat had his rear left leg amputated after a severe trauma which we think was from being hit by a car. after the amputation the surgery site had full necrosis and infection, which led to further surgeries. finally everything is healing nicely and he had the stitches out a week ago. after researching what i'm witnessing, it seems like he's dealing with phantom leg throughout the day. he'll be fine one moment and cruise down the hallway and jump on to a couch, then other moments he'll go into a tense body spasm with cries and hissing, sometimes falling over. you can tell in these moments that he's trying to use the missing leg. 

i've seen on here some thoughts of prescription pain treatment and i'm wondering how to go about this, and other treatments i can do at home? i'm also wondering if there's a rough time frame of how long phantom leg can be an issue? he's a little over a month from the amputation at this point. 

thanks! 🙂
