Jerry the sugary bully cat

I'm new to CatSite forum, just earlier I posted "Funeral for a friend" on the rainbow bridge. I lost my best friend Groucho a week ago, and wanting a new playmate for Charlie the black cat, I adopted a rescued cat, Jerry. He is a very sweet black and white shorthair, looks about a year old, has had all his shots but is not NEUTERED yet---he will be first thing Monday morning.
The PROBLEM: he is aggressive toward Charlie, and in fact already outweighs him. I don't want him to run off Charlie, who is still mourning for Groucho (as are we all). Will the neutering fix this "bully" behavior, or do I need to find Jerry a new home? All advice welcome, I'm very concerned!

Neutering will definitely help the issue. Intact toms are aggressive by nature, so they can secure the lovely ladies in the area.

It sounds like they haven't gone through a "formal" introduction? This article: I'd Like You To Meet... gives a good step by step of the ideal way to introduce new cats into a household. Cats don't usually do well when they are just put together without a chance to get used to the idea first.

I'm so sorry for Groucho I can't go in the bridge forum because it upsets me too much

I always thought when i brought Sophie into the house as a kitten 11 months ago that Rosie (who had just turned 2)would take to her straight away?!.

How wrong i was She hated not only Sophie by hissing and growling at her, but she did the same to me as well(she is a tortie though and we all know they have attitudes!! ).

Thankfully Rosie accepted Sophie after 2 weeks but all cats are different and may take longer, but Heidi has given you a great link to help you

Let us know how it goes!
