My cat is 14. Very healthy, inside/outside. Recently she has seemed constipated and I have switched her dry food diet to a mix of wet/dry. She's also more lethargic and has become very "licky". I've just called the vet and they say to take her in. She absolutely loathes the carrier box and it takes her ages to recover.
I'm googling overly. Could this be diabetes? Of course I'll take her if she is unwell but it'll be a taxi both ways and her obvious distress.
