If I had tenants that were otherwise quiet, weren't a public nuisance and they aid their rent on time - I'd want to keep them!
I'd wxpect yo do minor repairs after a tenant moved on.
(I did have nightmare tenants once - I would never want to repeat the process.
If the 2 cats aren't playing loud music until 4am. Fighting/shouting in street, putting old furniture and rubbish in garden....id happily let them stay
All of this!
Our last tenants let their kid put stickers onto the F&B painted kitchen island
.
They also pulled up the weed membranes up from the small allotment in the garden, never grew anything, and never deweeded it, leaving the weeds at about 3ft high.
Left dog shit all over the lawn.
Put the wrong rubbish in the wrong bin, so I had to go through both and sort before the binmen would collect it.
Moaned that the oil heating was too expensive and wanted us to fit a new boiler. There was nothing wrong with it!
Complained that the gardener (part of the tenancy, paid by us) was too noisy. I've yet to source a silent petrol mower 
Were constantly late with rent.
We served a section 21 as we wanted to sell the house and thought it best to sell empty - they then didn't pay rent towards the end of the tenancy because 'the deposit would cover it'!!!!
After they left, it cost us nearly £3k in mates rates to get the garden and house sorted and cleaned.
Seriously, if cats and a few drilled holes is all that's upsetting you, think really hard before serving notice.
