Hello there,
I recently posted a thread about my new cat being aggressive (hissing and growling) towards the old one. Well, the hissing is practically gone, now they tolerate each other although they're not best friends... they sometimes "play" together pawing each other through the door crack, but that's it. They've been in "full contact" for almost 2 weeks.
Nevertheless, 2 days ago my old cat was lethargic, sleeping almost all day long, didn't want to eat nor play. The following day he ate, but not as much as he usually does. Today he ate more, but still, I took him to the vet. He said he's fine physically, but he thinks it's stress, even though the cats have been living together "fully" for 2 weeks. Why behave like this after 2 weeks?
What should I do? He still sleeps a lot and doesn't play, but eats some, uses the litter box normally, etc. Should I consider getting a Feliway diffuser? Has it worked for those with more than one cat, even after weeks since their introduction?
P.S.: the new cat is a 7 months old female, and the old one is a 3 year old male. Both sterilised.
