My cat was in a cattery for two weeks and returned with vomiting and diarrhoea. The cattery deny she was ill. The vet did blood tests early this week, a scan of her tummy and said everything was clear. They rehydrated her on an IV drip overnight. Still being sick and diarrhoea I took her to a new vet who gave her a steroid, antibiotic, appetiser via injections injection and I have a paste to give her to support her gut microbiome. He also took a urine sample and said there’s a tiny bit of protein but nothing concerning/that would cause a UTI so she’s clear. The vet was bit perplexed having examined her and said it could be the stress of being in a cattery for the first time. She still has diarrhoea a week since picking her up from the cattery. Has anyone else experienced this? She’s on my 1 years and healthy. Has anyone experienced a stressed cat following cattery? Any tips?
