Happy New Year litter tray! Bit worried about Zara today. She's normally a very hardy, healthy cat, never really been ill in her 5 years of life. The past couple of days she's had diarrhea - not terribly, just once or twice a day, and in the tray. I wormed her yesterday, and started her on a probiotic last night - I think there's some improvement as no bm overnight, but is there anything else I should be doing before she goes to the vet tomorrow? (Her booster is due anyway so got to take her). Also, will they do the booster if she is not 100%?
