I got a 2nd cat back in May from someone off Facebook (after local shelters didn't have any cats that could live with another cat). I was told she was around 2 years old and had been feral for her first year; her previous owner didn't neuter her. I named her Jelly (because I didn't like her other name and my other cat is called Peanut). I've tried to get her spade but it's taken until now for her to warm up to me (she's practically a baby now); the first week she bit me so hard there was blood everywhere and I had to get a tetanus shot - so she's not spade yet and won't be until I think she won't try and murder the vet. Jelly's an indoor cat, and when she goes into heat around every 3 weeks she tends to spray on things; I never smell anything until I accidentally put my hand in it or pick up something she's done it on, and it's always sticky and sweet smelling? Almost as if I'd spilt cola or something and let it dry a bit. I tried Google but it just kept telling me that when a female cat sprays it's this foul smell - but Jelly's isn't like that. As far as I can tell she's healthy, maybe a bit skinny but she did go a long while of only eating once a day until she stopped being scared of me. I'm looking to take her to be spayed as soon as I think she'll be comfortable enough, but if this is a known sign of something that needs medical attention I'll take her asap.
