Hi, picked up a small cat about 2 1/2 yrs old from previous owner in Feb. Told me she only ate kibble. She was tiny. Since then I've fed her wet foods and she looks a lot bigger (normal size) now. On heat driving me nuts as in an apartment so had her spayed. Past few weeks she has got a LOT more vocal and hungry. Always crying for food. Constantly waking me up at 5am - a lot more 'aggressively' crying/miaowing - so i get up and give her a full pouch of food (i did try ignoring her for week or so, didn't work). Before I could go back to bed and get another hour sleep before she's crying again (for play maybe), but now it's straight after eating. still hungry, bored, wanting play, or something wrong? And throughout the day she is constantly hungry. Driving me up the wall and also concerned something is wrong. Toying with idea of another cat to keep her company, but could this make things worse? Is say four pouches of felix a day above the norm? House cat but I think she longs to go outside! Any tips to relieve boredom? She has a few toys and I do play with her but she's just so much more vocal lately and getting pretty annoying.! Oh, and she's not as affectionate as before - a bit more colder towards me now!
