Is there anything i should be doing for lawn?

Is there any things i can be doing now to start getting lawn nice again for summer, the cats are going to toilet on it all the time :( i gave it a mow yesterday, and unsure of any things i should do and at what months to get a lovely lawn again. thanks

 

Autumn/winter feed now.

early March spring feed/mosskiller and then 2 weeks later scarify out the dead moss.

Cats poohing probably due to not finding a nice border for a litter tray.

 

I wouldn't say much is required at the moment, other than keeping it tidy and a bit of light mowing if needed

 

Why is that ? Is moss such aggressive to be harmfull for lawn.
In my country (Milan countryside, Italy) moss does not seem to be too aggressive... Probably because, due to the climate of the region, moss is not widespread over here. (although it does exist).
Is that the case ?
Over here, much more aggressive seem to be weed...
But those start growing in late spring, if I am not wrong...

 

That's for sure...
Due to the different latitude, in England more tilted sunrays generates longer shadows... (but less head-aches because of sunrays straight over the heads as it occurres to we the italians...:()
