The study was carried out by the university's vet studies school
Rivalry with another cat is the biggest source of feline anxiety closely followed by moving home or the arrival of a new member of the owner's family.
Experts compared 31 cats with bladder disease to 24 healthy cats in the same households and used a control group of 125 other healthy cats.
