I have added new pictures and information to my posts.

They always have plenty of dry food and water!.

Their names are Panda (black and white) and Nancy (Tabby)
And I love them to bits and they love and trust me😀

Brief update! I have insomnia, then normal sleep length, (also called non 24 hour sleep disorder. .....Look that up if you want!) and I often sleep in the daytime    Which is why I can’t feed them wet food regularly.
LOL I’ve just thought! They sleep and wake when they want and so do I. !!! ha ha!

Picture of them eating

For the time being I have decided to take my cues from them.
As previously written they were given 4 pouches a day, often all at the same time, plus an unlimited amount of dry (due to a sleep problem I have, I often can’t feed them twice a day)
They are not perturbed if the wet food is many hours old if it is still wet and not dried up, as sometimes when I feed them the next day I will leave the previous day’s leftovers out and they will eat that as well as the fresh food.
I have recently been putting down 2 pouches once a day, and that is almost all being eaten, also they still have an unlimited supply of dry food.

I would leave good quality dry food out in a bowl- for them to graze on all day.  I would then only offer wet food once a day to start with.  Offer a small amount and if they are hungry they will eat it.  Most cats like their food fresh, straight from the packet.  My guys get wet food in the morning and again at tea time.

Good luck

Let us know how you get on

Thank you for your suggestions.
