That's Alfie a male tuxedo. Look at the long whiskers. We adopted him from Misty's last litter. He was definitely past the kitten stage when we took him in. He once caught three squirrels in three days. The last one he was eating in the backyard. His hunting skills passed down from Misty. Putting him in the cat carrier the first time proved to be a challenge. I have bigger than normal carriers suitable for a small dog and the carrier also opens up from the top to make it easier. I also wear thick winter gloves so I don't accidentally get scratched then it's off to the vet's. Prior to putting a cat into the carrier I close off as many access to escape points as possible as things get more difficult when they go under a bed say. Everyone else at the vet's have smaller regular carriers of different styles suitable for their Cuddles or Fluffy so I kind of stand out in the waiting room.
FLEAS imo are the #1 affliction or problem for cats although some of my cats never seem to get fleas at all while others are hard hit. Can even lead to severe forms of dermatitis although other things like stress or ingredients in their diet can lead to severe skin allergies in some cats as well. Many times at that point the vet will give a cortisone shot combined with an antibiotic shot. I once spoke with a medical director of a vet clinic since retired and she said fleas can actually develop an immunity to some flea medications. Ever notice how some flea meds don't help the situation? I don't know if hers is a minority view but it's food for thought. Revolution is the strongest flea med on the market but has to be prescribed first. Pricey stuff. Horticulturally speaking and far less expensive some plants like marigolds and catnip repel the little bloodsuckers. I'm not lucky in the green thumb department but marigolds are the easiest plant to grow.
