Kitten had diarrhoea at 7 weeks just prior to first vaccinations. Vet wormed kitten and next day he poo'd out a long worm. He was on chicken, fish & scrambled egg diet for a week and all seemed well. Vet delayed vaccination for a week, at which point his diarrhoea had stopped and he'd put on 200g in weight. He's now due 2nd vaccination & 2nd worming tablet end of this week but has started to have a small amount of blood in his poo again, and slightly loose poo, over the last couple of days. Taken me until today to spot which kitten as we have a litter. Is this likely to be related to worms? He's well in himself, eating & drinking well, playing and running around like his siblings. just wondering if i should take him to vet tomorrow to investigate or as he's known to have had worms wait until Friday when he'll be wormed again.
