HELP ME!! CATS

[lisad123]

I have 2 lovely cats, but this last 2 weeks we have had 2 stray cats come into the house though the window and they have sprayed in my house. I cant seem to get rid of the smell, any hints? Also can anyone suggest a way to stop them coming in??
I dont want to shut the window as my cats often use this way to come and go as they please.

TIA

Use a solution of biological washing detergent for the smell - never any ammonia-based cleaners as this just exacerbates it

do i just mix with water?

Cat flap - magnetic one or microchip one? I'm having the same probs at the moment with another cat coming in and scaring my kittens/ chasing them up unreachable trees, breaking new normal catflap. Vastly annoying!

I would love to put a cat flap in, but I have a conswervatory the whole length of the back of my house, and its glass the whole way. Front door is glass too

I think you fit them into glass but it's expensive.

Yes, just mix up some biological washing powder or liquid with water and spray or wipe it on, leave it for a few minutes and then dry.
