Elderly cat approx 16 yrs old still active and likes to go outside, eats and drinks , no obvious signs of illness. I've just let him in at the back door and he wouldn't come in just sat there making a low growling noise. I lifted him in and put him on the floor and he seemed unable to walk properly and turn head. After a few minutes he crawled on his belly and occasionally carried on miaowing. His eyes looked all big . After about 10 minutes he seemed to come to a bit and took himself off to his bowl ate his biscuits and then crawled into his basket . All quiet now seemed to be breathing normally . Could this have been a mini stroke or something ? We live out in country so not near roads so hasn't been hit by a car .
