Is 7.5lbs for a 4.5-5 month old kitten over-weight?

He weighed 5.2lbs exactly a month ago when i got him neutered and now he weighs 7.5lbs. He gained more than 2 pounds in a month. Is that normal? I thought normally kittens gained 1lb per month. He looks almost like a big cat already and he's barely 5months old. He has a kitten face otherwise but his body is almost like a full sized grown cat. How much more will he grow? When will his weight/size become stable?

He may just be a big cat some end up gaining more naturally it all depends on the parentage. If you really want to know feel it's side you should be able to feel just a think layer of fat.

I am not one to ask.  My almost 6-month old cat weighed almost 9 lbs when he was neutered.    I started cutting back on his dry food and cut out one of his wet food feedings and that helped keep his weight in check at about 6 months of age.  He's now about 11 pounds at 5 years old. 

For your kitty, I'd continue feeding him as normal.  Weight and size usually even out by 18 mos of age. 

As long as he doesnt look too plump its fine.
