Long suffering .....

Dizz cat. 
Stevie hates the cat and wants to eat and or kill him

We have a routine

dog in, cat out
kitchen gate locked and cat in ...... eats dinner
living room door shut so cat can get upstairs without fear of death
bedroom door open enough for cat to get in
Dog distracted

Great that cat trusts me to know the routine like a military operation to keep him safe.

Bed time, dog crated so cat can roam free, not be eaten and have loves and cuddles.

and ultimately wind the dog up.
Mad thing is Barney and Diz cat are best friends
