My cat is 16 and is ill. Going into the utility room - where she sleeps - there was a strong smell of urine. She has also dribbled on the sofa. I have smelt her bed and it doesn't smell too bad but it stands to reason she has probably dribbled in there too. Given her age and illnesses will it cause her stress to get a new bed or will the fact that it is all new and nicer smelling make it okay? I have tried washing her pad a while ago but the fur doesn't come off and it just makes the nest 3 washes get covered in her fur.
