I have a lovely ginger cat who seems healthy, today i saw it pooping outside and it seemed to have a runny tum, i thought maybe it could be caused by worms (2 weeks ago i saw a worm, bought a tablet from the vets but he only ate half of it), so i thought i would try the bob martins spot on wormer, i had to pin the cat down to put it on (he did get a little stressed) and then 5 minutes after he started making odd noises and foaming at the mouth, he then jumped onto the stair gate and almost looked as though he was in a trance (blank), he eventually got down and started scratching where the worm solution was so i wiped it off with a wet cloth.
Was it a reaction to the worm treatment or could there be something else wrong? (maybe whatever is causing to runny tummy)?
Should i take him to the vets? (i realy cant afford the £25 just to walk through the door but if he's poorly then i will have to take him).
He seemed ok half an hour after i wiped it away and was led outside sun bathing. He's outside now but ate some food before going out (so seemed ok).
