i always check on their poo poo to see worms or not. but ofcourse, you need to see them doing the process not after the process. can only see it while the poo poo is fresh.sometimes can see this short small white thinggy moving on the stool.
from your question above, i can see that stuart get the worms from outside activities. since you mention rubbish right. ouch thats alot. when he poo poo inside the house, and suddently another cat poo poo also, the worms that come out from stuart can actually move to the other cat.
outdoor cat has more worms than indoor cat.
for kitten, worms are transferred from them via their mom. during pregnancy and also during nursing the kitten, the worm will transmitted.
for adult cat, worms can be transmitted by:
- ingestion of soil and plant material contaminated with worm
- Exposure to feces containing worm
- Ingesting fleas that harbor worm
- Eating contaminated prey such as mice and birds
- get it from another cat, the worm can travel to your cat.
and etc.
For your info, when you mention "WORMS", you actually need to be specific on what worm.. there are few types of worms in cat:
- Tapeworms (These cat worms are rather flat in appearance and can range in size from less than an inch up to about two and a half yards.)
- Heartworms
- lungworms
- roundworms (These intestinal parasites resemble a piece of spaghetti, and are the most common type of worms found in pets.)
- hookworms (These worms are named for the hook-like teeth they use to attach themselves to your cat's intestinal walls. These parasites feed on blood, causing diarrhea and anemia.)
- get it from another cat, the worm can travel to your cat.
and etc.
